Which term is a negative ion made of oxygen and hydrogen?

• A. Hydrogen ion (H+)
• B. Base
• C. Hydroxide ion (OH-)
• D. Salt

Answer: (C)

This is about identifying a negatively charged ion formed from oxygen and hydrogen. The term is hydroxide, written OH−. It’s a polyatomic ion made of one oxygen and one hydrogen atom that carries a -1 charge. Hydrogen ion (H+) is just a bare proton with a positive charge, a base is a broad category of substances that can increase pH or donate hydroxide in some cases but isn’t the specific ion, and a salt is an entire compound composed of positively and negatively charged ions. hydroxide is the specific negative ion composed of oxygen and hydrogen.
