Why does ammonia act like a base?
(select those that apply)
it combines with h+ions.
ammonia releases oh-ions.
it increases the oh-concentration.
it dissociates easily.

It combines with H+ions.

Explanation: It combines with H+ions.

Ammonia releases ions.

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydronium ions in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Ammonia being a lewis base donates lone pair of electrons and thus combines with . Also aqueous solution of ammonia gives ions in water, thus act as Arrhenius base.
