Metal Carbonate vs. Metal Hydrogen Carbonate: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on January 21, 2024
Metal carbonates are compounds formed from a metal and carbonate ions, while metal hydrogen carbonates are formed from a metal, hydrogen, and carbonate ions.

Key Differences

Metal carbonates consist of metal ions and carbonate ions (CO3^2-), whereas metal hydrogen carbonates, also known as bicarbonates, include an additional hydrogen atom (HCO3^-).
