Chromium and cadmium can be removed from wastewater by treatment
with sodium hydroxide.
Show the net ionic reactions of Cr3+(aq) with
NaOH(aq) and Cd2+(aq) with
NaOH(aq).
a) Cr3+(aq) reacts with NaOH(aq)
b) Cd2+(aq) reacts with NaOH(aq
Homework Answers
Cadmium and chromium will both react with Sodium hydroxide to form a precipitate.In both equations, Na+ will not be involved in the reaction and act as an intermediate species and will not appear in the net ionic equation.
a) Cr3+ (aq.) + 3 OH- (aq.) 
Cr(OH)3 (s)
b) Cd2+ (aq.) + 2 OH- (aq.)
Cd(OH)2 (s)
