Question
One litre of solution contains 10-5 moles of H+ ions at 25oC. Percentage ionisation of water in solution is :
Options
A.1.8 × 10-7 %
B.1.8 × 10-9 %
C.3.6 × 10-9 %
D.1.8 × 10-11 %
Solution
In this solution, source of OH- is water
∴ Cα = [OH-]
α =
= 1.8 × 10-11 M
% ionisation = 1.8 × 10-9 M
∴ Cα = [OH-]
α =
= 1.8 × 10-11 M% ionisation = 1.8 × 10-9 M
