Question
A solution of Na2CO3 is added drop by drop to litre of a solution containing 10-4 mole of Ba2+ and 10-5 mole of Ag+, if KSP for BaCO3 is 8.1 × 10-9 and KSP for Ag2CO3 is 6.9 × 10-12 then which is not true:
Options
A.No precipitate of BaCO3 will appear until [CO32-] reaches 8.1 × 10-5 mol per litre
B.A precipitate of Ag2CO3 will appear when [CO32-] reaches 6.9 × 10-5 mol litre-1
C.No precipitate of Ag2CO3 will appear until [CO32-] reaches 6.9 × 10-2 mole per litre
D.BaCO3 will be precipitated first
Solution
For precipitation of Ag2CO3. [CO32-] = 
= 6.9 × 10-2
and for precipitation of BaCO3. [CO32-] =
= 8.1 × 10-5
= 6.9 × 10-2 and for precipitation of BaCO3. [CO32-] =
= 8.1 × 10-5 Create a free account to view solution
