Question 24 1 pts Write the solubility product constant expression for calcium phosphate, Ca3(PO4)2 O [Ca2+][PO43-M[Ca3(PO4)2] O Ca2+1*[PO43-12 O [Ca2+][PO43-1 O [Ca2+12[PO43-13

Answer 1

Dissociation of calcium phosphate take place as follows-

Ca3(PO4)2 --------> 3Ca²⁺ + 2PO4^3-

Ksp = solubility product constant.

Solubility product expression for above reaction can be written as-

Ksp = [Ca^{​​​​​2+}]³ [PO_{​​​​​4}^{​​​​3-}]²

^{This is the correct expression for solubility product.}

^{Hence correct option is (b).}
