When solid potassium cyanide $(KCN)$ is added to water,then:

Do you expect different products in solution when aluminium $(III)$ chloride and potassium chloride are treated separately with $(i)$ normal water,$(ii)$ acidified water,and $(iii)$ alkaline water? Write equations wherever necessary.

Which of the following aqueous solutions will have the highest $pH$?

Which of the following salts is $NOT$ derived from a weak acid and a weak base?

It is found that at $25\,\text{°C}$,$0.1\,M$ solutions of four sodium salts $NaA$,$NaB$,$NaC$,and $NaD$ have the $pH$ values $7$,$9$,$10$,and $11$ respectively. Which one of the corresponding acids is the strongest?

The $pH$ of an aqueous solution of $CH_3COONa$ of concentration $C \ M$ is given by:
