In which of the following reactions, an increase in volume of the container will favour the formation of products?

For the chemical reaction $$3X(g) + Y(g) \rightleftharpoons X_{3}Y(g)$$ the amount $$X_{3}Y$$ at equilibrium is affected by

$$K_a$$ value for the acid $$HA$$ is $$1\times 10^{-6}$$. The value of $$K$$ for $$A^- +H_3O^+ \to HA +H_2O$$ is

Aqueous solution of $$HNO_3, KOH, CH_3COOH$$ and $$CH_3COONa$$ of identical concentration are provided. The pair(s) of solution which forms buffer upon mixing is (are)

The hydrogen ion concentration of a slightly acidic water solution can be represented by

When $$NH_4Cl$$ is added to $$NH_4OH$$ solution, the dissociation of ammonium hydroxide is reduced. It is due to:

Pure $$NaCl$$ is prepared by saturating a cold saturated solution of common salt in water with $$HCl$$ gas. The principle used is

Out of the following which pair of solutions is not a buffer solution?

$$K_{a1},K_{a2}$$ and $$K_{a3}$$ are the respective ionisation constants for the following reactions:
$$H_{2}S\leftrightharpoons H^{+}+HS^{-}$$
$$HS^{-}\leftrightharpoons H^{+}+S^{2-}$$
$$H_{2}S\leftrightharpoons 2H^{+}+S^{2-}$$
The correct relationship between $$K_{a1},K_{a2}$$ and $$K_{a3}$$ is,

What will be the ionisation constant of formic acid if its 0.01 M solution is 14.5% ionised?
