Acid Base Chemistry – FAQ
An acid is a substance that donates a proton (H⁺) to another substance in a chemical reaction. Acids have a pH less than 7 and can turn blue litmus paper red. Common examples include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄). They often taste sour and are corrosive.
A base is a substance that accepts a proton (H⁺) or donates an electron pair in reactions. Bases have a pH greater than 7 and turn red litmus paper blue. Common examples include sodium hydroxide (NaOH) and ammonia (NH₃). They often feel slippery and can be caustic.
When acids and bases react, they form water and a salt in a neutralization reaction. This occurs because hydrogen ions (H⁺) from the acid combine with hydroxide ions (OH⁻) from the base, creating water (H₂O). The remaining ions form the salt. For example, HCl and NaOH react to form water and sodium chloride (NaCl).
The pH scale measures the acidity or basicity of a solution, ranging from 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic. The scale is logarithmic, meaning each whole number pH change represents a tenfold change in H⁺ concentration. It helps in understanding the properties and potential reactions of substances.
Buffers are solutions that resist changes in pH when small amounts of acid or base are added. They are crucial in maintaining stable pH levels in biological systems, such as blood, which must stay around pH 7.4. Buffers work by neutralizing excess H⁺ or OH⁻, ensuring that the system’s pH remains relatively constant.
