Laboratory 13 Quality Control: Verifying the Concentration of Hypochlorite (CIO) in Bleach Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which...

Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which is the active ingredient in bleach. Oxidizing and reducing agents are often determined using a redox titration....

please can you answer questions part one
Vitamin C can be measured using a technique called titration. Because vitamin C is easily oxidized, we can use this chemical reactivity to detect it in solution. If we react vitamin C with iodine, the vitamin C is oxidized and the iodine is reduced. Iodine (12 molecules) form a purple complex with starch in solution, but reduced iodine, iodide, (I-) is colorless in the presence of starch. CH,OH CH,OH о о снон Η...

If you can please explain step by step for each question.
Problem 1, Question 1.
Cyclohexae, C6H12, melts at 6.55 oC and has a freezing point
depression constant of kfp = -20.0 oC/m (where m
is molality). You want to determine the molar mass of an unknown
pure compound using the colligative property of freezing point
depression. You weigh out 83.561 g of cyclohexane, and confirm that
its melting point is 6.55 oC. You then mix 2.566 g of your...
