Question

Hydrochloric acid solution A and B have concentration of 0.5N and 0.1N respectively. The volume of solution A and B are required to make 2 litres of 0.2N hydrochloric are:-

Answer 1

let the ratios of 0.5N and 0.1 N be x and 1-x respectively

0.5x  + 0.1(1 - x) = 0.2

0.5x + 0.1 - 0.1x = 0.2

0.4x = 0.1

x = 0.2/0.4

  = 0.5

Volume of 0.5N = 0.5 x 2 = 1 litre

Volume of 0.1 N = 0.5 x 2 = 1 litre
