Acids

An acid is a type of chemical substance that has a sour taste and is capable of turning blue litmus paper red. Acids are corrosive and can react with certain metals to produce hydrogen gas. They are also known for their ability to neutralize bases.

Properties of Acids:

• Acids have a sour taste.
• They turn blue litmus paper red.
• They react with metals to produce hydrogen gas.
• Acids are electrolytes - they conduct electricity when dissolved in water.
• When mixed with bases, they neutralize each other and form salts and water.

Examples of Acids:

Some common examples of acids include hydrochloric acid (HCl), sulfuric acid (H₂SO₄), acetic acid (found in vinegar), and citric acid (found in citrus fruits).

pH Scale:

The strength of an acid is measured on the pH scale, which ranges from 0 to 14. Acids have a pH less than 7, with lower numbers indicating stronger acidity.
