Hydrogen carbonate, also called bicarbonate, is an acid salt formed from carbonic acid and contains hydrogen carbonate ions. Most hydrogen carbonates are thermally unstable and decompose into ...
The hydrogen ion concentration is a measure of the acidity of seawater and is commonly expressed on the pH scale; the lower the pH, the higher the hydrogen ion concentration and the acidity of ...
A white precipitate forms if sulfate ions are present. Explain why, in a test for sulfate ions, the sample is acidified with hydrochloric acid first. Carbonate ions also produce a white precipitate ...
