Physical & Chemical Properties of Acids

Physical Properties of Acid:

1. Acids have a sour taste, e.g. lemon, grapefruit and sour milk.

2. Acids are electrolytes, i.e. their aqueous solutionA solution in which the solvent is water is referred to as an aqueous solution. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For... More conducts electricity.

3. Concentrated forms of acid are corrosive, e.g. trioxonitrate(V) acid, hydrochloric acid and tetraoxosulphate(VI) acid.

Always add acid to water. Not water to acid, because the hot acid solution may splatter onto your body and face and may cause serious burns.

Chemical Properties of Acid:

1. Their aqueous solution turns blue litmus paper to red due to the formation of hydroxonium H₃ O⁺ in hot water

HCl + H₂ O_(l) →  H₃ O⁺ _(aq) + Cl^– _(aq)

In chemistry, hydronium is
