According to the Arrhenius concept, an acid is a substance that . Group of answer choices can accept a pair of electrons to form a coordinate covalent bond all of these statements tastes bitter causes an increase in the concentration of H in aqueous solutions is capable of donating one or more H

 an increase in the concentration of in aqueous solutions and  is capable of donating one or more

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 hydrogen 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.

Thus According to the Arrhenius concept, an acid is a substance that causes an increase in the concentration of in aqueous solutions and  is capable of donating one or more
