Zirconium phosphate [Zr 3 (PO 4 ) 4 ] dissociates into three zirconium cations of charge +4 and four phosphate anions of charge -3. If molar solubility of zirconium phosphate is denoted by S and its solubility product by K sp then which of the following relationship between S and K sp is correct ?
Options
- AS = K sp / 6 9 1 2 7
- BS = K sp / 1 4 4 1 / 7
- CS = K sp / 6 9 1 2 1 / 7
- DS = K sp / 6 9 1 2 1 / 7
Correct answer
D. S = K sp / 6 9 1 2 1 / 7
Step-by-step solution
In the saturated solution of Zr 3 PO 4 4 + aq ⇌ 3 Zr 4 + 3 S molar + 4 PO 4 3 - 4 S molar K sp = Zr 4 + 3 PO 4 3 - 4 = 3 S 3 4 S 4 = 2 7 × 2 5 6 × s 7 = 6 9 1 2 S 7 S = K sp 6 9 1 2 1 / 7
