Question

Calculate normality of 2.1 weight by volume h2 s o4 solution

Answer 1

Explanation:

21% w/v H2SO4 means 21 g of H2SO4 is present in 100 ml of solution.

No. of equivalents of H2SO4 = weight / Gram equivalent of H2SO4

= (21 / 49) moles

Normality = (Equivalents × 1000) / Volume of solution

= [(21 / 49) × 1000] / 100

= 4.28 N
