Answer:
base, raises
Step-by-step explanation:
An acid is a substance that, when dissolved in water produces hydrogen ions as the only positive ion. In solution, an acid is a substance which produces hydronium (oxonium ) ion i.e
as the only positive ions.
A base is a substance that will neutralize an acid to yield salt and water only.
According to Bronsted lowry; an acid donates an electron and a base accepts the electron. According to Bronsted lowry; in aqueous solution, the reaction of an acid with a base constitutes a transfer of a proton from the acid to the base.
in aqueous solution, hydrogen ion H⁺ combines with the water molecule to form the hydronium (oxonium ) ion
which in turn increase in pH level of the aqueous solution
i.e.
↔
