The solubility product of PbCl ₂ at 298 ~K is 3.2 10⁻⁵ . What is its solubility in mol dm ⁻³ ?
Options
- A8 10⁻⁶
- B2 10⁻²
- C5.6 10⁻³
- D5.0 10⁻²
Correct answer
B. 2 10⁻²
Step-by-step solution
aligned & K _ sp =3.2 10⁻⁵ & PbCl _ 2( ~s ) Pb _ ( aq ) ²⁺+2 Cl _ ( aq ) ⁻ & K _ sp =4 ~S ^3 & 4 ~S ^3=3.2 10⁻⁵ & ~S = [3] 3.2 10⁻⁵ 4 & = [3] 8 10⁻⁶ & =2 10⁻² ~mol dm ⁻³ & aligned
