Question

Water can act as either a(n) _____ or a _____.

acid, base
solute, solvent
anion, cation
salt, mixture

Answer 1

Water can act as an acid and a base. As an acid, water donates H+, the hydrogen ion. As a base, water donates OH-, the hydroxide ion.

Answer 2

Answer;

-Acid, base

Step-by-step explanation;

-A water molecule can act as an acid or a base even in a sample of pure water. It acts as an acid (donates H+) when it reacts with a stronger base, say sodium hydroxide.

-Water acts as a base (accepts H+) when it reacts with a stronger acid, say hydrochloric acid. If the medium is water, water, having a pH of 7, is considered neutral.
