The K s p for the following dissociation is 1.6 × 1 0 - 5 P b C l 2 ( s ) ⇌ P b ( a q ) 2 + + 2 C l ( a q ) - Which of the following choices is correct for a mixture of 300 mL 0.134 M P b ( N O 3 ) 2 and 100 mL 0.4M NaCl?
Options
- AQ < K s p
- BQ > K s p
- CQ = K s p
- DNot enough data provided
Correct answer
B. Q > K s p
Step-by-step solution
Q = Pb 2 + Cl − 2 = 300 × 0.134 400 100 × 0.4 400 2 = 3 × 0.134 4 ( 0.1 ) 2 Q = 1.005 × 1 0 - 3 Hence, Q > K s p
