# $H_2S$ will precipitate the sulphide of all the metals from the solution of chlorides of Cu, Zn and Cd if

(a) the solution is aqueous
(b) the solution is acidic
(c) the solution is dilute acidic
(d) none of the above solution is present

If the solution is aqueous i.e. it does not contain any acid, $H_2S$ will precipitate the sulphides of all the metals from the solution of chlorides of Cu, Zn and  Cd.
