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).
Added by Juan Francisco W.
Step 1
The reaction of Cr3+(aq) with NaOH(aq) can be written as follows: Cr3+(aq) + 3OH-(aq) -> Cr(OH)3(s) The net ionic equation, which only shows the species that actually participate in the reaction, will be the same because all ions are involved in the reaction. Show more…

Chromium(III) hydroxide and lead(II) hydroxide are typical amphoteric hydroxides. (a) Write the formula unit, total ionic, and net ionic equations for the complete reaction of each hydroxide with nitric acid. (b) Write the same kinds of equations for the reaction of each hydroxide with an excess of potassium hydroxide solution. Reference to Table $10-1$ may be helpful.
