Overview
Acids, bases, and salts are fundamental substances that we encounter daily in our food, medicines, and household products. Acids taste sour and turn blue litmus paper red, while bases taste bitter and turn red litmus paper blue. Salts are neutral compounds formed when acids and bases react together.
Key Concepts
Indicators are dyes or mixtures
Indicators are dyes or mixtures of dyes that change colour to show whether a substance is acidic or basic. Natural indicators include litmus (purple d
When acids react with metals
When acids react with metals, they produce hydrogen gas and a salt. The general equation is: Acid + Metal → Salt + Hydrogen gas. For example, zinc rea
Metal carbonates and metal hydrogencarbonates react
Metal carbonates and metal hydrogencarbonates react with acids to produce carbon dioxide gas, salt, and water. The general equation is: Metal carbonat
Neutralisation is the reaction between
Neutralisation is the reaction between an acid and a base to form salt and water. The general equation is: Acid + Base → Salt + Water. At the ionic le
All acids produce hydrogen ions (H⁺)
All acids produce hydrogen ions (H⁺) in aqueous solutions. These hydrogen ions combine with water molecules to form hydronium ions: H⁺ + H₂O → H₃O⁺. A
