Answer 1

a) A subtance that increase H3O+ concentration when it is dissolved in water.

Step-by-step explanation:

Arrhenius acid: any species that increases the concentration of H+ ions (or protons) in an aqueous solution.

Arrhenius base: any species that increses the concentration of OH- in an aqueous solution.

Brønsted-Lowry acid: any species that donates protons.

Brønsted-Lowry base: any species that is accepts protons.
