Question

Identify the effect of increasing acidity on the solubility of the given compounds. ca3(po4)2

Answer 1

Solubility of
`Ca_(3)(PO_(4) )_(2)` will increase.

Step-by-step explanation:

As the basicity decreases solubility increases. The more basic an ion is in the acidic solution more will be its solubility as its concentration will be decreasing or used up in the solution.

`Ca_(3)(PO_(4) )_(2)` is a basic in nature. On addition of an acid to this basic salt would contribute in increasing the solubility of the compound.

`Ca^(+2)+ PO_(4)^-^3+ H^+ \rightleftharpoons H_(3) PO_(4)`

Thus basicity is being reduced thereby increasing the solubility of the solution.
