One of the key goals of analytical chemistry is to determine composition of a specific source of matter and there are numerous ways to do so depending on the type of matter that is being studied (Analytical Chemistry, n.d.). For example, one method that is used frequently in analytical chemistry is titration. The purpose of this was to utilize and become familiar with the methods and techniques of titrating and weighing, because precision and accuracy is key. A titration utilizes a solution referred to as the titrant, which is a solution that has a know concentration, that is added drop wise to another solution in which the concentration is not known (Titration, 2016). The titrant is also often referred to as the primary standard and it …show more content…
Then the burette was filled with the NaOH solution created from part one and the initial volume was noted. Next, 0.7g of KHP was obtained and placed in an Erlenmeyer flask where it was mixed and dissolved with 25mL of deionized water. After the KHP finished dissolving 4 drops of indicator, phenolphthalein, was added to it. Lastly, the titration was conducted by added the solution from the burette into the Erlenmeyer flask until the solution turned pink for approximately 15 seconds, which indicated neutrality. Once the solution turned pink the final volume in the burette was noted and used to calculate the concentration of the NaOH. A total of three of the same titrations were …show more content…
Once the titrations was initiated at first the was no change, however about half way through pink began to appear where the NaOH was added and then disappeared. Once the solution was neutral it became a very light pink, but if to much NaOH was added it resulted in the solution becoming darker pink. This would result in excess addition of NaOH, which would result in a larger percent
Chemistry is the most fascinating science to me. Chemistry applies to all things in the universe; living or non-living. Everything is made of elements which are made up of atoms of a certain atomic number. Thereafter I took AP Chemistry, I knew I had to choose a career in the field of chemistry. I understand and enjoy learning about chemistry. Chemistry is important, interesting, and ever expanding. Therefore, I must pursue a career in Chemistry. Having a degree in chemistry opens the door to a
and difficult. During my first year, I took general academic courses. Within my second year, I focused on the basics required for medical practitioners. My third year was mainly concentrated on the theoretical and practical background of Clinical Chemistry, Urine analysis, and other courses. Although my overall score in Biochemistry was not so high as my other scores, I was pleased to see my diligent effort did not go to waste. By the time I was in my fourth year, I mastered most of the manual techniques

After undergraduate school is completed, along with internships and a Masters Degree is earned . A Graduate Recommendation Exams (GRE) is required to be passed to enter a Universities graduate school. With a Graduate 's school programs
work of Henry Louis Le Chatelier. Le Chatelier studied chemistry extensively in school and made great discoveries as a teacher of the science at colleges in France. He is most known for the principle named after him: Le Chatelier’s Principle, which I will go into detail with later in the paper. My goal in this paper is to bring to light the significance of Le Chatelier’s life and his work in the field of chemistry and science. To achieve this goal I have organized my paper into four sections. The first
From herbalists during the prehistoric era to the modern-day medicine we have now, bio-medicine has always been a key science. The billions of microorganisms we are exposed to every day suggest that the possible event of contracting an illness is to be expected. Despite this, some illnesses can be treated with a small amount of acetaminophen, modern-day paracetamol. The fact that a possibly lifesaving compound exists in a small pill that can be easily obtained without prescription fascinates me.
their illness. As a child I could not grasp how one illness evoked another, it was only when I learned about the science behind the human body that I seriously began analyzing my childhood experiences. Further studies in Biology and Chemistry allowed me to develop analytical skills and Physics and Math promoted my deduction skills in following logical processes to infer results. I have learned that the history of optometry is a heroic narrative that speaks of a similar quest to identify the links that
When analyzing literature, it is essential to understand the material from all the perspectives in order to get the intended information. There are several methods and techniques such as the critical analysis of the material and reading analytical reviews on the content. In addition, Mallon and Kirsch argue that there exists a relationship between authors and their writings and therefore, an understanding of the authors’ background can influence the perspective, views and opinion of the readers (1)
I can, I will & I must. These words have been key point behind my learning. It has helped me to frame my targets & reach the goals of my carrier, which I strongly believe in materials science. The modern world is loaded with ballistic variations in gadgets & devices, with miniaturization being the ace of the cards. With the technology getting bigger the demand for Nano devices has been larger and Materials Sciences & engineering has a lion’s share in accomplishing it. This extrudes me to think beyond

Men and women are psychologically different in many ways. Some of these differences include competitiveness, goal orientation, self-confidence, motivation, mental toughness, incentives, preferences, etc. According to Anne Bowker in Sports Participation and Self-Esteem, Men have an advantage over women in sports because they're more aggressive and have higher self-esteem (2003). There has always been that stereotype of boys being more athletic than girls. The gender segregation of sports reflects
