question 3 please

1) What does "standardization" mean? Why do you need to do this? It is the process of determining the exact concentration (molarity) of a solution. The purpose of standardization is to determine the concentration of the titrant. It helps us eliminate errors in analysis and gives us accurate results. 2) is the quantity 50mL important? What would happen if you used 250mL ? How will you accurately measure out 50mL ? 3) Why are you putting iodine solution in the buret, and titrating the vitamin C sample, instead of putting the vitamin C sample in the byret, and titrating a sample of iodine? What do you think would happen if you did this
