Question

When 1 molecule of calcium phosphate is added to water, what and how many ions are formed? remember that ions are charged and so you must indicate the correct charge on each ion to receive credit for this question?

Answer 1

Asnwer :When 1 molecule of calcium phosphate is added to water, total 5 ions are formed 3 ions of Calcium($Ca^{2+}$) and 2 ions of Phosphate($PO_{4}^{3-}$)

Explanation : When Calcium phosphate is added to water it gets dissociated into ions. Calcium phosphate ($Ca_{3}(PO_{4})_{2}$) dissociates into 3 ions of Calcium $Ca^{2+}$ and 2 ions of Phosphate $PO_{4}^{3-}$.

Dissociation equation of calcium phosphate is :

$1 Ca_{3}(PO_{4})_{2} \leftrightarrow 3 Ca^{2+} + 2PO_{4}^{3-}$

From the dissociation equation we can conclude that total 5 ions are formed when 1 molecule of calcium phosphate is added to water.
