Question description

A solution that may contain Cu^2+, Bi^3+,Sn^4+, and/or Sb^3+ is treated with thioacetamide in an acid medium. The black precipitate which forms is partly soluble in strongly basic solution. The precipitate which remains is soluble in 6M HNO3 and gives only a blue solution on treatment with excess NH3. The basic solution, when acidified, produces an orange precipitate.

(2) Which are absent? 

(3) Which are in doubt?
