The correct answer is the First ion: Ba²+; the Next test: is NaOH (1 drop then excess).

Unknown solution + NaSo4 → White precipitate

A precipitation reaction is a chemical phenomenon that occurs in aqueous solutions when two ionic bonds combine to form an insoluble salt. A precipitate is an insoluble salt formed during the precipitation process.

A Precipitation reaction is often a double displacement phenomenon that forms a precipitate, a residue in solid form. When two or more solutions with different salt concentrations are combined, these reactions form insoluble salts that precipitate out of solution.
