Which of the following sulphides dissolve in yellow ammonium sulphide?

A $As X_{2} S X_{3}$
B $SnS$
C $CuS$
D $Bi X_{2} S X_{3}$

Answer: A, B

As X_{2} S X_{3}

(acidic) and

SnS

(after oxidation by polysulphide to

SnS X_{3} X^{2 -}

) dissolve.

Bi X_{2} S X_{3}

and

CuS

are group IIA sulphides and are insoluble.
