1.	At 25^(@)C, 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)
Answer» HA is a weak acid The ionization constant `(K_(a))` of acid is approximately `10^(-6)` at `25^(@)C`. 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 Solution :N//A
