Titration

Purpose: By doing this experiment, students will properly complete a redox titration well also determining the amount of hypochlorite ions present in the commercial bleach given. Introduction: Commercial Bleach and other commercial products like hair colouring agents, contain oxidizing agents. Oxidizing agents are substances that remove electrons from one or more reactants and thereby oxidizes it, whereas reducing agents are substance that give electrons to other reactant. There is some…

The experiment performed provided insight on the importance of acid-base interactions and the pH of solutions that are involved in a variety of aspects including industrial, environmental, and biological contexts. Back titration was used to determine the number of moles of HCl acid that were neutralized by a single tablet of several variations of commercial antacids. In theory, the antacid that neutralized the largest number of moles of acid was found to be the most effective. The results…

the first green colour appeared. The concentration of hydrochloric acid was found to be 0.2508 mol L-1. Introduction Standardisation is a process which is carried out to determine the actual molarity of a solution. Titration is a technique that is often used in standardisation. In titration, a solution is…

Introduction This accuracy lab of titration report experiment will discuss how to find the unknown substance molarity. By using some of the lab equipment to help guide and identify the molarity of the unknown substance. I believe that it will take around three hundred drops of sodium hydroxide (NaOH) for it to be able to reach to its endpoint of the unknown substance. My reason behind my hypothesis is… Methods In this lab experiment we use a buret to…

As it is required that you rely on the human eye to determine when the indicator displays the end-point of the titration. Repeating an experiment using alternate equipment is crucial in revealing the accuracy of the titration. Different equipment assists in eliminating almost all forms of systematic errors. However, time constraints often determine whether or not this can be achieved, and in this case, there was not…

The purpose of this experiment was to prepare and standardize a sodium hydroxide solution as well as determine the molar concentration in as strong acid and the percent by mass of acetic acid in vinegar. We used volumetric analysis, also known as titration, in both experiments. The average molar concentration for NaOH was 0.2749 mol/L while the average molar concentration of the acid solution was .2493 mol/L.The average percent by mass of acetic acid in vinegar was found to be 12.3 %…

Determining Percent Composition of Unknown Copper Ore Sample Iodine-thiosulfate Method: An Analytical Method The objective of this experiment is to eliminate all interfering species from a sample of unknown copper ore in order to later determine pure copper content. Copper ore can be found in a mineral that contains pure copper and other species that is mined and can later have copper extracted from them (Taher, 1999). To eliminate all interfering species, such as Iron, Arsenic, and…

Introduction Acid-base titrations are used to calculate properties of an acid or a base by titrating them with a strong Acid or base. In a titration, certain amount of volume of one substance usually a strong acid or base, a titrant, is added to another substance, an acid or base of some kind, until a change in properties are observed. Strong acids and bases are used because they allow the neutralization reaction between the acid and base into salt to go to completion. By titrating an unknown…

As the titration of the two different vinegars were completed by different people, the techniques we used may be different therefore the results may be different than if it was completed by the same person. The experimenter may have misread equipment such as the…

The purpose of today’s lab was to determine how effective antacids are at neutralizing HCl. This experiment required us to place 3 antacids tablets into 3 Erlenmeyer flasks. Next we were required to add 50.00 mL of 0.500M HCl and five drops of phenolphthalein. Finally, we needed to titrate NaOH into the flasks. Each antacid brand required a different amount of NaOH in order for it to be completely titrated. The data collected from the experiment allowed each group to calculate the cost…
