Copper Compounds and Hydroxide Ions

The video tutorial explains how to name the compound CuOH. It begins by identifying the components: copper, a metal, and OH, a polyatomic ion, forming an ionic compound. The name of the metal, copper, is written first, followed by the hydroxide ion. Since copper is a transition metal with variable charges, the charge must be determined. The hydroxide ion has a charge of -1, indicating copper's charge is +1. Therefore, the compound is named Copper(I) Hydroxide, with the Roman numeral indicating the charge of copper.

What type of compound is CuOH?

• Ionic compound
