Questions 1 1 Wiitle a balanced equation for the oxidation of isoborned by 2what do you actually observo in a positivo K-st hiir? What does . 3. What is the purpose of adding NaHSO, at the end of the by NaOG NaDC mentioned at the end of the first paragraph in the Experimental Procedure s a positive KI-starch tos?What does & mean & tho K3-sarch tost mentioned at ond of tho first paragrapl, in the is positive? oxidation? Wihe a balanced Wite a balanced equation for the reaction that it undergoos.

Explanation / Answer

1] Balanced reaction :

C10H18O + NaOCl C10H16O + NaCl + H2O

2] White paper turns blue because the Iodine attaches to the sugar.

It means there is an excess of the oxidizing agent.

3] The purpose of adding NaHSO3 at the end of the oxidation is to quench the excess oxidizing agent NaOCl.

NaHSO3 + NaOCl ----> NaCl + NaHSO4
