Which of the following is a definition of a base? o a. behaves as a catalyst. o b. accepts h ions from acids. oc. turns cloudy when dissolved in water o d. donates h ions when dissolved in water o e. releases heat when dissolved in water

b. accepts ions from acids

Explanation:

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 ions and a base is defined as a substance which accepts ions.

Here water is donating ions, and thus act as acid and ammoia is accepting ions from water and thus is a base.

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.

Thus base is a substance which accepts   ions from acids.
