An investigation into whether the voltage affects the amount of gas produced during the electrolysis of sodium chloride solution.
Prediction:
I think that hydrogen gas will be produced due to the half equation
2H +2e àH this will be produced at the cathode because opposites attract and the hydrogen ions are positive. At the anode I think that chlorine will be produced due to the half equation 2CL -2e àCL the chlorine ions are negative so they are attracted to the positive electrode. I also think that as the voltage is increased the amount of hydrogen gas produced will increase this is because of a series of scientific equations: if the voltage is increased the current then is increased, this is because of ohms law, V=IxR, where the voltage is proportional to the current, if the current is increased the charge then increases because Q=IxT. The number of moles of electrons=charge
-:- 96500, this is Faradays constant from his 2nd law. The relationship between the amount of substance deposited at an electrode and the number of electrons that are passed around a circuit (current) can be used to calculate the expected volume of substance produced at the electrode. To find the amount of hydrogen gas produced at the electrode we would multiply the number of moles of hydrogen gas by 24, this is the area that one mole of any gas will occupy. Then I will have to multiply by 1000 to get the amount of hydrogen in cm³.

Too big to measure
I am going to use voltages 5,6,7,8,9 and10 because for voltages lower than five there was not a lot of gas produced this made it extremely difficult to measure the amount of gas. For voltages over 10 there was too much gas produced and it went out of both sized measuring tubes. I decided to do it for 2 minutes as this figure seemed to be the one where the results were at their best, they were easily measurable unlike the results for one and three minutes.

Michelangelo was an Italian-born artist in 1488. Not too long after his birth, he was apprenticed to Ghirlandaio for three years, where Michelangelo learned elements of fresco technique and produced replicas of past Florentine masters. By the age of 16, Michelangelo was already producing his own style of art that were shown in his two relief sculptures. The following years after the death of Lorenzo de’ Medici in 1492, Michelangelo traveled and created more artwork. Some of the artworks produced were a wooden crucifix for the high altar for the Hospital of Sto Spirito, and marble statuettes for the Arca di San Domenico.
Michelangelo was a painter, sculptor, poet, and architect. He was born March 6, 1475, and he passed away February 18, 1564. He is considered to be one of the most brilliant artist during the renaissance time period. His full name is Michelangelo di Lodovico Buonarroti Simoni.
An architect, poet, sculptor, and painter are some of the terms that define Michelangelo di Lodovico Buonarroti Simoni. Michelangelo was one the of the most influential artists of his generation. He was born in Caprese, Italy on March 6, 1475 and died in Rome on February 18, 1564. Michelangelo’s early life and work consisted of him becoming an apprentice to Domenico Ghirlandaio, a painter in Florence, at the age of 13, after his father knew that he had no interest in the family business. The painter then moves on and joins Lorenzo de’ Medici’s household, where he learns and studies with the painters and sculptors that lived under the Medici roof. As a sculptor Michelangelo carved magnificent statues, he was invited to Rome

Amongst the several intellectual and artistic Renaissance individuals, this figure “saw the angle in the marble and carved until he set him free.” Artist Michelangelo Buonarroti learned his art while young and under the occupation of Lorenzo de Magnificent; his talent was pooled in different directions, but he applied himself to traditional religious matters with great devotion, although he had been increasingly attracted to the classical legends he heard at home. Michelangelo was born with talents beyond artistry; he is mostly known as being a painter and sculptor, but Michelangelo was also an architect, poet, and engineer.

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.
Michelangelo’s full name is Michelangelo di Lodovico Buonarroti Simoni. He was born on March 6, 1475 and passed away on February 18, 1564 at the age of 88 (Biography). Michelangelo was a painter, sculptor and architect during the Italian Renaissance period (History). His work demonstrated a variety of psychological insights, physical realism and intensity, During that time, Michelangelo received commissions from some of the most wealthy and powerful men as well as the Catholic Church to create art pieces for their homes or buildings. His works, including the “Pieta” and the “David statues, and the ceiling paintings of Rome's Sistine Chapel (Biography). Michelangelo was born in a family with a banking business and that allowed him to have an
Electroplating Experiment Aim To find the amount copper gains or loses on the electrodes using different amounts of current each time during electrolysis. How the changing of current affects the electroplating of copper. Introduction Electroplating is generally carried out in order to improve the appearance or corrosion resistance of the surface of a metal by electrodepositing a thin layer of metal ion on it. The metal substrate to be coated is made by the cathode in an electrolytic cell. The cell used in electroplating contains an electrolyte which is usually an aqueous solution containing a reasonably high concentration of an ion of the metal which is to be electroplated on the surface.
Every research study should describe the methods used for collecting, analysing and interpreting data. Research methodology is a systematic solving of the research problem and includes all the tools and methods used in the research process.
Michelangelo lived from 1475-1564. He was arguably one of the most inspired creators in the history of art. As a sculptor, architect, painter, and poet, he had a tremendous influence on his contemporaries and on following Western art in general. Michelangelo’s father, a Florentine official named Ludovico Buonarroti with connections to the ruling Medici family, placed his 13-year-old son in the workshop of the painter Domenico Ghirlandaio. After about two years, Michelangelo studied at the sculpture school in the Medici gardens and shortly thereafter was invited into the household of Lorenzo de’ Medici. He became acquainted with such humanists as Marsilio Ficino and the poet Politian, who were frequent visitors. Michelangelo produced at least two sculptures by the time he was 16 years old, the Battle of the Centaurs and the Madonna of the Stairs. This shows that he had achieved a personal style at a very early age. His patron Lorenzo died in 1492, two years later Michelangelo fled Florence, when the Medici family was temporarily expelled. He settled for a time in Bologna where he sculpted several marble statuettes.
