An acidified solution of is saturated with . What is the minimum molar concentration of required to prevent the precipitation of ?
Use and overall dissociation constant of , .
Step 1: It is given that , , solubility product , overall dissociation constant of , .
Step 2: We know that,
Step 3: So,
Now, dissociation of is
So,
Putting the values in the equation,
we get,
Therefore, the minimum molar concentration of required to prevent the precipitation of is .
