The characteristics of an acid include:
1. Sour taste: Acids generally have a sour taste, like lemons or vinegar. However, it is important to note that tasting acids can be dangerous and should be avoided.
2. Reactivity with metals: Many acids react with metals, producing hydrogen gas and a metal salt. For example, hydrochloric acid reacts with zinc to produce zinc chloride and hydrogen gas.
3. Ability to turn blue litmus paper red: Acids can change the color of certain indicators. Blue litmus paper, for example, turns red when exposed to an acid.
4. Conductivity: Acids are often electrolytes, meaning they can conduct electricity when dissolved in water. This is due to the presence of hydrogen ions (H+) in the solution.
5. Reactivity with bases: Acids react with bases to produce a salt and water. This is known as a neutralization reaction. For example, when hydrochloric acid reacts with sodium hydroxide, sodium chloride and water are formed.
6. Corrosive: Strong acids can be corrosive, meaning they can cause damage to living tissues, metals, and other materials.
7. pH less than 7: Acids have a pH value less than 7 on the pH scale, which measures the acidity or alkalinity of a substance. The lower the pH value, the stronger the acid.
