• Anion

• Base

• Acids

• Ionic compounds

An ionic compound that produces hydroxide ions when dissolved in water is called a:

• Cation

• Binary compound

• Polyatomic ion

Any atom or group of atoms that has a positive charge is known as a:

• Anion

• Cation

• Monatomic ion

• Law of multiple proportions

Compounds composed of metals and nonmetal anions are called:
