Le Chatelier's principle is not applicable to

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.

Le-Chatelier's principle is applicable only to a
