Expert Solution

Step 1:

We’ll answer the first question since the exact one wasn’t specified. Please submit a new question specifying the one you’d like to get answered.

Ionic product of water is defined as the product of the concentrations of the ions present in an aqueous solution. It is represented by the symbol $K_{w}$ and its value is equal to $10^{- 14} M$ .

Dissociation of water in the solution:

$2 H_{2} O \to H_{3} O^{+} + O H^{-}$

Expression of ionic product of water:

$K_{w} = [H_{3} O^{+}] [O H^{-}]$
