Question

On boiling n÷5 hcl the volume of the aqueous solution decreases to 250 ml ...

Answer 1

Answer:N\2.5

Explanation: gram per litre is equal to normality in 2 gram equivalent weight is equal to n by 5 input 86.5 is equal to 36.5 / 5 is equal to 7.3 gram HCL into 1 litre and by 5 HCL

HCL left after boiling 7.3-3.6 v is equal to 3.6 v HCL left in 250 ml solution

As per according to normality formula is equal to weight of solute in 2003 equivalent weight into volume in ml

Is equal to 3.65 2500/30 6.5 into 250 is equal to n divide by 2.5

Hence proved ....thank you
