In last week’s experiment, the standardization of potassium permanganate and the titration of iron salt were utilized in order to figure out the percent of iron within a redox reaction. The examination revealed that the molarity of KMnO4 is indeed .02M and the percent of iron salt in the unknown salt (Tarzan) is around 20.92%. The results were both precise and accurate in both parts of the experiment. This is because the standard deviation and percent RSD in both experiments are very low. This suggests that the numbers obtained are very close to each other which implicates the numbers are precise. The data is also accurate due to the fact that the numbers are what was expected and the reaction produced a pale pink color like it was supposed to. The data was also compared to other groups who had the same salt and both groups acquired identical or similar results. These findings enable the group to can reject the null hypothesis which was the percent of iron would be high and accept the alternative hypothesis which was the percent of iron would be low.

Reduction-oxidation (redox) reactions are a type of reaction that transfers electrons from one ion to another. Within these reactions, electrons are transferred from one reactant to another in which they either gain or lose electrons during the reaction. A product that has gained an electron is said to have been reduced, while products that have lost electrons are said to have been oxidized. During a redox reaction, there are two types of agents which are the oxidizing and reducing agent. The oxidizing agent is the reactant that gains electrons and the reducing agent is the reactant that loses electrons during a reaction.
There is a rule within redox reactions and that rule is, th...

... the figures are also accurate. Not only did the experiment work according to the lab manual, but the team compared results with other groups and the data acquired was either very similar or identical. The fact that other groups had similar numbers means that the data is not only precise but accurate.
CONCLUSION
In this experiment, the standardization of potassium permanganate and the titration of iron salt were utilized in order to figure out the percent of iron within a redox reaction. Based on the data attained, the results illustrated that the percent of iron salt in the unknown salt (Tarzan) that was obtained through our professor was low with only about 20% of iron salt in the mix. All in all, the group can reject the null hypothesis which was the percent of iron would be high and accept the alternative hypothesis which was the percent of iron would be low.

Essay about Sodium Chloride As Salt For The Body

- Sodium chloride also known as salt, is a very important nutrient to the body because it can help the body control blood pressure, it also helps the body with the proper functioning of the muscles, and it helps the body with the communication of the nerve impulses (1). Salt is also important because it is used in the daily diets. Salt doesn’t just help the body, but it also helps to bring out the flavors of the meals that people cook. Whenever people are sitting and watching television snacking on potato chips or eating pizza, salt is being consumed whether or not people are aware of it (1)....   [tags: Blood pressure, Hypertension, Potassium, Salt]

Standardization Of Evidence Care Processes Essay

- Another approach toward implementation of the EMR that is currently employed involves standardization of evidence care processes. According to Sheridan, the process of standardizing evidence-based practice care such as action plans and patient educational resources in the clinical setting is a fact that has been embraced by clinicians and found to be satisfactory (Sheridan, 2012). Adoption of standardized care resources ensures that an explicit quality comparison can be made with other players in EMR implementation....   [tags: Nursing, Evidence-based medicine, Standardization]

The Salt Range in the Punjab Region of Pakistan Essay

- 5.1 Introduction Structurally, the Salt Range is the result of tectonic forces imposed during the lateral phases of the Himalayan orogeny in the late Cenozoic time; the occurrence of the thick, incompetent Salt Range formation at the base of the sedimentary sequence has strongly influenced the structure. 5.2 GENERAL STRUCTURES OF THE PAIL-BAHDRAR AREA Structural features were essentially the result of gravitative flow process (a tectonic diaprisim) involving the subsurface flow of highly incompetent sequence of the Salt Range formation, which consists of red crystalline gypsiferrous marls, gypsum, anhydrite, salt lenses and occasional dolomites and oil shales, due to differential loading cau...   [tags: hill system, rock salt]

The Trade Commission Vs. Morton Salt Essay

- In the business world, price discrimination can be detrimental to small businesses trying to compete with larger organizations pricing. In the 1930s congress was worried about large multimarket firms using predatory marketing techniques in certain markets to bankrupt smaller firms in the area. In response, Congress enacted the Robinson-Patman act which prohibits larger forms conducting pricing strategies that contribute towards becoming a monopoly by getting rid of their rivals, the smaller family owned stores....   [tags: Pricing, Price, Cost, Morton Salt]

The Elements and Health Benefits of Potassium Essay

- Potassium is an element on the periodic table that is symbolized by the letter K. The atomic number of this element is 19. At room temperature this element is a solid. Potassium can be found in two forms: either pure or compounds. Pure potassium is described as a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive in water However, Potassium forms many compounds such as Potassium chloride, which is the most common potassium compound (Gagnon, 1). This form of Potassium is especially used in fertilizers as a salt substitute....   [tags: atomic number, forms, chemistry]

Lab Report on Volumetric Determination of Iron with Potassium Permanganate

- Lab Report on Volumetric Determination of Iron with Potassium Permanganate Principle: This experiment consists of titrating the ferrous ion with permanganate ion to study the oxidation-reduction reaction. The ions react in acidic solution to give ferric ion and a reduced ionic form of manganese. All the reactants and products except permanganate ion are weakly colored, whereas permanganate is a very intensely colored ion. Then a solution of permanganate is removed as long as there is a ferrous ion present to react with it....   [tags: Papers]

Titration Investigation Essay

- Titration Investigation Aim: The aim of my investigation is to determine the solubility of calcium Hydroxide solution with the aid of the titration process. Titration can be defined as the method of determining the concentration of a substance in solution by adding to it a standard reagent of known concentration in carefully measured amounts until a reaction of definite and known proportion is completed, as shown by a color change or by electrical measurement, and then calculating the unknown concentration....   [tags: Papers]

Essay on Potassium

- Potassium Potassium is a vital element in the human body. Potassium had never been distinguished between sodium until the eighteenth century. Before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis of chloride or hydroxide....   [tags: essays research papers fc]

Essay about Titration

- Titration Titration is a laboratory technique by which we can use to determine the concentration of an unknown solution using a standard concentration of another solution that chemically reacts with the unknown. This standard solution is referred to as the "titrant". We have to have some way to determine when the reaction is complete so you add indicator to the unknown so you can see when the reaction is complete. This is referred to as the "end point" or more technically the equivalence point....   [tags: Papers]
