I am doing a titration lab using sodium thiosulfate pentahydrate to determine an amount if iodine. I'm having issues setting up the balanced equation to determine the mole ratio of iodine to thiosulfate.
I used an approximate .080M solution of Sodium Thiosulfate and then titrated into a flask containing 25mL of KIO3, 20mL H2SO4 and 2g KI. Final mL of Sodium Thiosulfate used to complete titration was 37.36mL of Na2S2O3 5H20. I then did the same process for a 25mL juice sample with a final burret reading of 36.42mL sodium thiosulfate used; and with an unknown sample, 23.75mL sodium thiosulfate used. I need to determine the following:
1. Exact molarity of sodium thiosulfate solution based on standardization titration data.
2. Concentration of Vit C (ascorbic acid) in unknown sample
3. Concentration of Vit C (ascorbic acid) in juice sample
I'm not sure how to calculate the actual molarity of my sodium thiosulfate and how that relates to the concentration of ascorbic acid

Suppose you need to standardize a sodium thiosulfate solution for a titration experiment. To do so, you will react it with a solution of iodine. You add a 1.00 mL aliquot of 0.0200 M KIO3 solution to a flask, followed by 3 mL of distilled water, 0.2 g of solid KI, and 1 mL H2SO4. You then titrate the solution with sodium thiosulfate solution in order to determine the exact concentration of Na2S2O3. The end point of the titration is...

I'm doing a titration lab tomorrow and I am not sure what the
formulas are to calculate the moles of NaOH, the moles of
HCl, and the molarity of HCl.
The objective of this laboratory is to determine the molarity of
a hydrochloric acid solution using a known concentration of sodium
hydroxide as the titrant.
volume of HCl in flask: 25.00 mL
the net ionic equation for the reaction is:
H+(aq) + OH-(aq) --> H2O(l)

Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...
