Iodine reacts with aqueous thiosulfate ion in neutral solution according to the balanced equation 12(aq) + 25,03 -(aq) s4062(aq) + 27- (aq) how many grams of 12 are present in a solution if 35.20 ml of 0.150 m na2s2o, solution is needed to titrate the la solution?

0.67 g

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

According to stoichiometry:  

2 moles of require 1 mole of

Thus require= moles of

Mass of

Thus 0.67 g of iodine are present in the solution.
