At 25ºC, pH of a 0.01 M solution of a monobasic acid (HA) is 4. The correct statement(s) regarding HA and its given solution is (are)
- HA is a weak acid
- The ionization constant (Ka) of acid is approximately10–6 at 25ºC
- Increasing the temperature of solution would cause the pH to decrease
- Addition of 0.1 M HCl solution would lower pH by increasing degree of ionization.
Answer
(A) HA is a weak acid, (B) The ionization constant (K a ) of acid is approximately10 –6 at 25ºC, (C) Increasing the temperature of solution would cause the pH to decrease
