The electrolysis of copper sulphate solution and copper electrodes
Introduction:
For my GCSE Chemistry assessment I will be investigating the electrolysis of copper sulphate solution with the copper (ii) plates.
Aim:
My intention for this observation is to find out how the current has an effect on the mass of copper deposited in the electrolysis of copper sulphate and copper (ii) plates.
Safety Precautions:
In this investigation I will make sure that everything is as safe as possible and that there are no chances of accidents occurring.
(1) I will wear safety glasses and a lab coat to avoid any danger.
(2) I will tie my hair back, which will prevent any accidents from occurring. (3) I will keep the area around me clear to prevent any accidents from occurring. (4) Benches should be tucked under the table so that nobody trips over. (5) As copper sulphate indicates the symbol, which means toxic, I will be careful that it is kept away from my skin and I am not able to smell it. The reason for this is that it can cause death.
(6) Copper sulphate will be placed in the tray at all times so that if it spills it will only spill in the tray.
(7) I will not keep the power on more than 10 minutes, as keeping the power on for too long can change the resistance of the wire.
(8) As the copper sulphate is dangerous I will wash my hands after each experiment.
Apparatus:
The apparatus that I require in this investigation is:
(1) Measuring cylinder- This will be used to measure 150ml of the copper sulphate solution
(2) Ammeter- This will be used to se how much current is flowing through the circuit
(3) Stop watch- This will be used to time how long the practical will be on for.
(4) Auto...

I know that this is a straight line graph and that the gradient is positive by looking at the graph. I can now interpret from this graph that this investigation matches the law of Michel Faraday, the first law that I mentioned in the scientific background knowledge is:
The quantity of electricity passed is proportional to the amount of substance discharged at an electrode.
This law infant matches my results that I have gained, I can now confidently say that the results that I obtained were accurate. As I increased the voltage and the current there was a larger mass in the cathode. Therefore this proves that my prediction which I made is correct: As the current increases the amount of copper deposited will also increase. In this electrolysis both the oxidation and reduction reactions have been used, the oxidation in the anode and the reduction in the
cathode.
Susan B. Anthony was indeed a strong, driven, and disciplined woman who had a great desire and passion to abolish slavery. Upon meeting Elizabeth Cady Stanton she became immersed in the women's rights movement, dedicating her life to obtaining equal rights for all. Many men pursued Susan but she never married, she did not want to be "owned" by a man. Instead she chose to dedicate her entire life to this cause.
Susan Brownell Anthony, being an abolitionist, educational reformer, labor activist, and organizer for woman suffrage, used her intellectual and confident mind to fight for parity. Anthony fought for women through campaigning for women’s rights as well as a suffragist for many around the nation. She had focused her attention on the need for women to reform law in their own interests, both to improve their conditions and to challenge the "maleness" of current law. Susan B. Anthony helped the abolitionists and fought for women’s rights to change the United States with her Quaker values and strong beliefs in equality.
Susan B. Anthony believed that women should have the same rights as men. She fought for this right in many different ways, but she is most famous for showing civil disobedience by voting illegally. Unfortunately, Anthony fought all her life for women’s rights, but her dreams were not fulfilled until 14 years after she died (“Susan” Bio).
...re and an American hero she devoted her life to working towards equal rights for all women. Through writing, speaking, and campaigning, Anthony and her supporters brought about change in the United States government and gave women the important voice that they had always been denied. Any study of feminism or women’s history would be incomplete without learning about her. She fought for her beliefs for 50 years and led the way for women to be granted rights as citizens of their country, Thanks to Anthony’s persistence, several years after her death, in 1920 women were given the right by the Nineteenth Amendment of the Constitution. I do believe she was the key figure in women getting the right to vote. “She will forever stand alone and unapproached, her fame continually increasing as evolution lifts humanity into higher appreciation of justice and liberty.”
Susan B. Anthony was a prominent women’s rights activist and a social reformer. She dedicated her life to spread awareness of the danger and unfairness of social inequalities and slavery. She helped creating or advocating many US and International organizations. She lobbied the creation of laws to protect the rights of citizens regardless of their ethnicity or gender. She was "one of the most loved and hated women in the country. "Her opponents often described her as "nsexed, an unnatural creature that did not function as a true woman, one who devoted her life to a husband” (Barry). She passed away
Susan B. Anthony (1820-1906) is considered one of the most influential figure in the women’s suffragist of her generation and has become an icon of the woman’s suffrage movement. Anthony is known to travel the country to give speeches, circulate petitions, and organize local women’s rights organization. Anthony was born in Adams, Massachusetts. After the Anthony family moved to Rochester, New York in 1845, they became active in the antislavery movement gaining more supporters across the country. In 1848 Susan B. Anthony was working as a teacher in Canajoharie, New York and became involved with the teacher’s union when she discovered that male teachers were paid more than female teachers a month. Her parents and sister Marry attended the 1848 Rochester Woman’s Rights Convention held August 2Anthony’s experience with the teacher’s union, antislavery reforms, and Quaker upbringing, established ground for a career in women’s rights reform to grow.
As an ambitious, disciplined, and devoted woman, Susan B. Anthony was a prominent women’s right activist who established the women’s suffrage movement in the nineteenth century and advocated equal rights for all women and men throughout her life. Born and raised in a Quaker family that considered women equal to men, Susan B. Anthony developed a sense of impartiality and wanted to ignite equality throughout all men and women. After teaching for fifteen years, Anthony became active in the temperance movement and the anti-slavery movement. However, since she was a woman, her right to speak publicly was denied which is one of the most significant concepts that encouraged her to become an effective woman’s suffrage leader. With the help of her
Susan B. anthony wasn’t as big as Martin Luther King Jr. or Abraham Lincoln but she nothing short of inspiring. One of her greatest speeches was Women's Rights to Suffrage in 1873. She was an agent for the Anti-Slavery Society and collected petitions when she was only 17. She was also president of the Congressional Union for Women’s Suffrage Organization (CUWO). She also helped with Fredrick Douglas and his situation.
Cassius Clay was the man that was easy to hate and easy to love. Cassius once said Clay developed his boxing style where he kept his hands down away from his face, and swinging. This is very unorthodox and not what boxers are taught to do. Cassius was the kid who did everything wrong, but still won. Cassius used his new style to his advantage by leaning back a fraction of a second before the opposing attack came. Cassius Clay was known as the Louisville lip because of his verbal intimidation. Others called him insane and said that he made these comments just for public attention to tell himself that he was better than the opposition. Cassius Clay once fought the big and scary Sonny Liston, who was picked by almost all experts to win. Clay taunted him the whole fight, the taunting wore Liston down physically and mentally as Liston lost by technical knockout in the seventh round. This fight gave him a lot of opportunities, but also gave him more haters who didn’t like his flamboyant and boastful
Volume's Effect on a Copper Sulphate Solution We are trying to find out if the current though a copper sulphate solutions volume is increased. To find this information out I shall perform an experiment using the following equipment; · 1 power pack · 1 beaker · 2 carbon rods for anode and cathode · 1 ammeter · 1 measuring cylinder · 2 crocodile clip wirers I shall also be using 60cm3 volume of copper sulphate in my preliminary results to decide upon the concentration of copper sulphate and the voltage I shall use. The following diagrams show the step by step process in which I will do my experiment; [IMAGE] [IMAGE] [IMAGE] [IMAGE] I will take 10 readings from 10cm3 to 100cm3. I will repeat my experiment to give my experiment a fair average. I will keep the power pack the beaker the carbon rods the crocodile clips the ammeter the concentration of copper sulphate and the measuring cylinder the same each time I do the experiment this experiment.
Don’t touch your face without washing your hands or cleaning them with alcohol-based hand sanitizer. Wash your hands often.
The aim of this investigation was to determine how five different metals of differing reactivity reacting with Copper Sulfate solution would affect the enthalpy change of the reaction.
of Copper Sulphate. To do this I plan to work out the amount of water
To investigate the temperature change in a displacement reaction between Copper Sulphate Solution and Zinc Powder
Electrolysis Investigation Planning In this investigation, I will assess how changing the electric current in the electrolysis of acidified water affects the rate at which hydrogen gas is produced. The solution to be electrolysed is made up using acid and water. It is of little consequence what acid is used however in this case I will use Sulphuric acid (H2SO4). When H2SO4 is put in water it is dissociated and forms ions: H2SO4 → 2H (2+) + SO4 (2-) Ions are also present from the water in the solution: H2O → H (+) + OH (-) During the electrolysis process, the positive hydrogen ions move towards the cathode and the negative hydroxide and sulphate ions move towards the anode.
