Solution

The mineral acid that forms a white precipitate with barium chloride is sulphuric acid (H₂SO₄).
When barium chloride is a salt that reacts with a dilute mineral acid, sulphuric acid, barium replaces the hydrogen and forms barium sulfate which can be observed as a white precipitate after completion of the reaction.
It is an example of a precipitation reaction between salt and acid.
$Precipitation reaction Salt + dilute acid \to Precipitate + Solvent {BaCl}_{2} + H_{2} {SO}_{4} (dilute) ⇢ {BaSO}_{4} (ppt) + 2 HCl (Barium chloride) (Sulphuric acid) (Barium sulphate) (Hydrochloric acid)$
