Answer:
base, raises
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 [tex]\mathbf{H_3O^+}[/tex] 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 [tex]\mathbf{H_3O^+}[/tex] which in turn increase in pH level of the aqueous solution
i.e. [tex]H^+_{(aq)} + H_2O_{(l)}[/tex] ↔ [tex]H_3O^+_{(aq)}[/tex]
