Relation between hydrolysis constant and dissociation constant are given. Which is the correct formula for MgCl_(2).

Answer»

`K_(h) = (K_(w))/(K_(a))`
`K_(h) = (K_(w))/(K_(b))`
`K_(h) = (K_(w))/(K_(a) XX K_(b))`
`K_(w) = (K_(h))/(K_(b))`

SOLUTION :For a salt of weak base and STRONG acid LIKE `MgCl_(2)`, the relation is as
`K_(h) = (K_(w))/(K_(b))`.
