Question

Substance A is added to water. After it is added, hydrogen ions are produced and accumulate in the

Answer 1

Substance A is an acid.

Substance B is a group of hydronium ions.

Explanation:

From the description above, we can deduce that substance A is an acid whereas substance B is a group of hydroxonium ions.

An acid can be defined as a substance that produces hydrogen ions in solution.

Acids interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution.

The hydroxonium ions results from the chemical bonding between oxygen of water molecules and protons released by the ionization of the acid:  

                    HCl + H₂O → H₃O⁺  +  Cl⁻
