If 1.27 g of iodine is liberated,when 10 ml solution of H2O2 is reacted with acidified KI solution.Then the volume strenghth of H2O2 is.?

Question

Ramreddy · Answer

N1V1= N2V2 N1 X 10 = 2.54/254 = 0.001 N Volume strength of H2O2 = 5.6 X Normality = 5.6 X 0.001 = 0.0056 Vol. &hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;... &hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;.&hellip;...

i didnt get the ans .the ans is 2.8

Ramreddy · Answer

Meq of H2O2 = Meq of I2

(w/34)*1000 = [1.27/(254/2)]*1000

w=0.34 g

Thus

0.34 g of H2O2will give =(11.2/34)*.34 =0.028 litre =28 ml

Thus volume strength of H2O2is = 28/10=2.8
