The concentration of [H+] and concentration of [OH–] of a 0.1 aqueous solution of 2% ionised weak monoprotic acid is [ionic product of water = 1×10–14]
A.0.02 × 10–3 M and 5 × 10–11 M
B.1 × 10–3 M and 3 × 10–11 M
C.2 × 10–3 M and 5 × 10–12 M✓ Correct
D.3 × 10–2 M and 4 × 10–13 M.
Explanation
We know that, degree of ionization can be found as- [ ] 100 /[ ] [ ] [ ]/100 [ ] 2 0.1/100 x x x H HA H HA H 3 w H 2 10 M K H OH x 14 3 10 2 10 OH x IONIC EQUILIBRIUM 34 14 3 12 OH 10 / 2 10 OH 5 10 x x
