QNEET-2017-Ch-950: NEET 2017 Chemistry - Class 11 NEET-2017-Ch-950 Solution: Concentration of the \(Ag^+\) ions in a saturated solution of…

Concentration of the Ag+Ag^+ ions in a saturated solution of Ag2C2O4Ag_2C_2O_4 is 2.2×10−4 mol L−12.2 \times 10^{-4}\ \text{mol L}^{-1}. Solubility product of Ag2C2O4Ag_2C_2O_4 is 2.66×10−122.66 \times 10^{-12} 4.5×10−114.5 \times 10^{-11} 5.3×10−125.3 \times 10^{-12} 2.42×10−82.42 \times 10^{-8}

Multiple Choice Options

  • A 2.66 ×\times _ 10 −- _ 12
  • B 4.5 ×\times _ 10 −- _ 11
  • C 5.3 ×\times _ 10 −- _ 12
  • D 2.42 ×\times _ 10 −- _ 8

Step-by-Step Verified Solution

Ag 2 C 2 O 4(s) _ 2Ag+ + C 2 O 4 2�       S                  2S           S K sp = [Ag + ] 2 [C 2 O 4 2� ] = [2S] 2 [S] [Ag+] = 2S = 2.2 _ 10 �4 or S = 1.1 _ 10 �4 M _ K sp = [2.2 _ 10 �4 ] 2 [1.1 _ 10 �4 ] = 5.3 _ 10 �12
