Substances which form hydronium ions (H_3O^+) in water are known as Arrhenius Acids.

Explanation:

According to Arrhenius' concept of acids, an acid is such a compound which when dissolved in water, releases proton(s) or H^+.

Now as an Arrhenius acid releases H^+, the proton combines with a H_2O molecule to produce a H_3O^+ ion which is an hydronium ion.

Examples of Arrhenius Acids -

HCl, H_2SO_4, HNO_3, HBr, HI, HClO_4
