Question

The K for the following dissociation is =1.6 ×10 . Which of the following choices is correct for a mixture of 300 mL 0.134 M Pb(NO ) and 100mL 0.4 M NaCl ? sp –5 3 2 sp sp sp sp 2 –5 3 2 2+

(A) Q > K
(B) Q < K
(C) Q = K
(D) Not enough data provided

Prashant Kotian · Accepted Answer

Correct answer: B) Q < K. Given K of PbCl = 1.6 × 10 Pb(NO ) : m moles = 300 mL × 0.134 M = 40.2 NaCl: m moles = 100 mL × 0.4 M = 40 This implies, [Pb] = M
