2079 Set H Q.NO. 13

The ionic product of water at [tex]$25^{\circ} C$[/tex] is [tex]$1 \times 10^{-14}$[/tex] and water is regarded as a very weak electrolyte.

i. Define the ionic product of water.

ii. Deduce the relation [tex]$K _w = \left[ H ^{+} \right] \left[ OH ^{-} \right]$[/tex].

iii. Calculate the [tex][tex]$[ OH^- ]$[/tex][/tex] concentration of 0.01 M HCl at [tex]$25^{\circ} C$[/tex].

iv. What is the effect of temperature on the ionic product of water?
