What is the composition of the precipitate formed when H2S gas is bubbled through 1.0 litre of a solution of 0.010 M Zn2+, 0.010 M Pb2+, and 0.010 M Mn2+, buffered at pH 2.0, until 0.10 mol of H2S has been added? (Ksp values are: ZnS: 1.6 × 10-23; MnS: 7.0 × 10-16; PbS: 7.0 × 10-29. For H2S, Ka1 = 1.0 × 10-7; Ka2 = 1.3 × 10-13 ).
