Ionic Equilibrium in Solution

Define solubility product ? Write solubility product expressions for the following:${\mathrm{Ag}}_2{\mathrm{Cr}}_2{\mathrm{O}}_7$

Explain the term ionisation.

Explain the term: ii) Dissociation

Explain the term: i) Extent of ionisation and on what factors it depends.

Explain the term: iv) Ionic equilibrium

Explain the term: iii) Strong and weak electrolytes

Explain the term: i) Non-electrolyte

Explain the term: i) electrolyte

${\mathrm{H}}_2\mathrm{O}+{\mathrm{H}}_2\mathrm{O}\rightleftharpoons {\mathrm{H}}_3{\mathrm{O}}^{+}+{\mathrm{OH}}^{-}$.The ionic product of water is $1\times {10}^{-14}$ at ${25}^{\circ }\mathrm{C}$ and $3.0\times {10}^{-14}$ at ${40}^{\circ }\mathrm{C}$. Is the above process endothermic or exothermic?
