Relation between hydrolysis constant and dissociation constant are given. Which is the correct formula for

\mathrm{MgC}{\mathrm{l}_2}

View answer and explanation

Correct option: B

{K_h} = \frac{{{K_w}}}{{{K_b}}}

Option B (

{K_h} = \frac{{{K_w}}}{{{K_b}}}

) is correct because

MgCl_2

is a salt of a strong acid (HCl) and a weak base (Mg(OH)2), so its hydrolysis constant is related to the base dissociation constant.
