Acids:

Substances which form ions while they are dissolved within water are known as electrolytes. There are three categories of electrolytes are bases, acids, and salts.

Acids are substances which dissociate in water to generate hydrogen (H⁺).  An instance of a general acid is sulfuric acid that is H₂SO₄.  In output, H₂SO₄ dissociates to form hydrogen and sulfate ions according to the following equation. A designation within parenthesis in the subsequent formulas denotes the state of the reactants and the products that is liquid (aq). solid (s), or gas (g).

H₂SO_4(aq) → 2H + SO₄

Further examples of acids are aspirin, vinegar, and lemon juice. These substances share the subsequent general properties.

1. Acid solutions taste sour (acid means "sour" in Latin).

2. Acids react with several metals to form hydrogen gas.

2HCI(aq) +   Zn(s) →           ZnCL2(aq)     +H2(g)

Acid                metal              metal salt       hydrogen gas

3. Acids turn litmus paper red.

4. Acid solutions conduct electricity.

5. Acids react with bases to form a salt and water.
