What gas is produced by mixing household bleach with vinegar?

Explanation:
The main idea is that acids reacting with a chlorine-releasing bleach produce chlorine gas. Household bleach is a sodium hypochlorite solution, and vinegar provides acetic acid. When acidic conditions are created, hypochlorite is converted to hypochlorous acid, which then reacts to form chlorine gas. A common overall form of the reaction is NaOCl + 2 CH3COOH → Cl2 + 2 CH3COONa + H2O. That’s why chlorine gas, not water vapor, oxygen, or hydrogen, is produced in this mixture. This gas is toxic, so mixing bleach with vinegar should be avoided.
