Question

An acidic solution of pH 6 diluted thousand times.The pH of solution becomes approx1)9 2)6

3)3 4)6.96

Answer 1

The pH is 6.96

REASON:

here due to dilution we need to consider effect of H2O. And as it is becomes aqueous solution so it contains some amount of H2O hence its pH increases (less acidic).

Therefore answer is :-

Given concentration of H+ ion is 10^-6 and on dilution to 100 times it becomes 10^-8

total concentration H+ = 1 x 10^-7+ 1 x 10^-6

=1 x 10^-7+ 10 x 10^-7 M

=11 × 10^-7

pH = -log [H+]

= 6.96
