Group III Analysis: Ni2+, Fe2+/3+, Cr3+ (Basic Hydrogen Sulfide Group)
The ions of Group III are precipitated as their sulfides, or as their hydroxides, from a basic solution of H2S.
To achieve a hydroxide ion concentration of the necessary concentration
Chemistry of the Separation and Identification of the Group I Cations
The precipitating reagent of Group I is a dilute solution of hydrochloric acid, and the ions
precipitated are those of silver, Ag+, and lead (II), Pb2+. The net ionic equations are:
