If solubility product of Z r 3 ( P O 4 ) 4 is denoted by K s p and its molar solubility is denoted by S , then which of the following relation between S and K s p is correct?

Options

  1. AS = K s p 144 1 6
  2. BS = K s p 6912 1 7
  3. CS = K s p 929 1 9
  4. DS = K s p 216 1 7

Correct answer

B. S = K s p 6912 1 7

Step-by-step solution

Z r 3 P O 4 4 s ⇌ 3 Z r + 4 3 s a q + 4 P O 4 3 - 4 s a q K s p = Z r + 4 3 P O 4 3 - 4 = 3 s 3 4 s 4 K s p = 6912   S 7 s = K s p / 6912 1 7
