(i). For a weak monobasic acid `K_(a)=10^(_5)` and `pH=5` then degree of dissociation of acid is `50%`
(ii). `[H_(2)SO_(4)]=0.1M" "V=400ml`
`[NaOH]=0.1M" "V=400ml`
on mixing these solution pH is approximately 1.3
(iii). Ionic product of water depends on temeprature
(iv). Le-chatelier's principal is not applicable for common ion effect.
Select the correct options:

Consider the following statements: (a) The pH of a mixture containing 400 mL of 0.1 MH_(2)SO_(4) and 400 mL of 0.1 M NaOH will be approximately 1.3. (b) Ionic product of water is termperature dependent. ( c) A monobasic acid with K_(a) = 10^(-5) has a pH =5. The degree of dissociation of this acid is 50% (d) The Le Chatelier's principle is not applicable to common-ion effect.
