Answer:
6.25 X10^{-9} = Ka
Explanation:
The ionic equation for the hydrolysis of the cation of the given salt will be:
The expression for Ka will be:
Ka =
As given that the concentration of the salt is 0.1 M and pH of solution = 4.7, we can determine the concentration of Hydrogen ions from the pH
pH = -log [H⁺]
[H⁺] = antilog(-pH) = antilog (-4.7) = 2 X 10⁻⁵ M = [MOH]
Let us calculate Ka from this,
Ka =
The relation between Ka an Kb is
KaXKb =10⁻¹⁴
