A thiosulfate ion solution was prepared by dissolving 4.5g of the Na2S2O3 compound. 5H2O in 250 ml of solution.
A) calculate the concentration of thiosulfate ions S2O3 2 - in the solution.
B) 150 ML of a diiode solution A are diluted up to volume 250 ml. The B solution obtained is dosed by the thiosulfate solution prepared above. The equivalence is observed when 7.25 ml of the thiosulfate solution is added to 10 ml of solution B.
