Question

30 ml of volume H2O2.40 ml of 20 volume H2O2.30 ml of 10 volume H2O2 are mixed .What is the normality of the mixture?​

Answer 1

$\mathfrak{\huge{\green{\underline{\underline{AnswEr :}}}}}$

H2O2 → H2O + 12O2

And, the volume of that solution taken was = 1 liter

Therefore, Normality = X/5.6

⚘ 30 volume H2O2 solution has molarity = 30/5.6 = 5.357M

⚘ 20 volume of H2O2 solution has molarity = 20/5.6 = 3.571M

⚘ 10 volume H2O2 solution has molarity = 10/5.6 = 1.785M

✿ Total Normality of Mixture

⇒ 5.357 + 3.571 + 1.785

⇒ 10.713M
