To the Pb(NO3)2 solution with dilute H2SO4 solution is added gradually, then
A
PbSO4 (s) is precipitated
B
Initially with the addition of dilute H2SO4 ,the solubility of PbSO4 is decreased
C
On addition of large excess of dilute H2SO4, again the solubility of PbSO4 is increased
D
All of the above would occur
Answer
All of the above would occur
Explanation
Solution
On addition of large excess of dilute H2SO4 the solubility of PbSO4 is increased because of the formation of soluble Pb(HSO4)2
PbSO4 + H2SO4 ¾® Pb(HSO4)2
