Question 1

Which metal sulfides can be precipitated from a solution that is 0.01 M in Mn2+, Zn2+, Pb2+ and Cu2+ and 0.10 M in H2S at a pH of 0.50?



◦ CuS
◦ ZnS, PbS, CuS
◦ PbS, CuS
◦ MnS

Question 2

A solution may contain the following ions Ag+, Cu2+, Cd2+, Mn2+, Ni2+ and Na+. A white precipitate formed when 0.10 M NaCl was added and after this was removed the solution was treated with H2S gas under acidic conditions and no precipitate formed. When the solution was made basic and again treated with H2S gas a dark colored precipitate formed. If no further tests were made then what conclusions can you draw?
◦ possible ions present Ag+, Mn2+, Ni2+, Na+
◦ possible ions present Ag+, Cu2+, Cd2+, Na+
◦ possible ions present Ag+, Mn2+, Ni2+
◦ possible ions present Ag+, Cu2+, Cd2+
