Which of the following are produced when a base is dissolved in water?
Irina-Kira [14]

Answer is: B. Hydroxide ions.

An Arrhenius base is a substance that dissociates in water to form hydroxide ions (OH⁻).  

For example sodium hydroxide: NaOH(aq) → Na⁺(aq) + OH⁻(aq).

Another example, balanced chemical reaction: Ba(OH)₂(aq) → Ba²⁺(aq) + 2OH⁻(aq).

According to the Arrhenius definition barium hydroxide is base.

Acids and bases when react (neutralisation) produce salt and water.

Like Sodium and Mercury and Lead &

Potassium. Look them up, & it will help you remember. Natrium, Hydragyrum, Plumbium et Kalium.
