ANSWER
Definition of an acid; is a substance that produced hydrogen ions (H+) as the only positive ion when dissolved in water or in an aqueous solution. it increases the concentration of hydrogen ions in an aqueous solution.
Definition of the base; are hydroxide compounds that give hydroxide ion (OH-) on dissociation in water. it increases the concentration of hydroxide ions in an aqueous solution.
Why do we use the definition: it helps us to understand the acid-base properties of substances in an aqueous medium. neutralization, hydrolysis, and strength of acids and bases
EXPLANATION:
Arrhenius defined acid and base in the following way
According to Arrhenius, he defined an acid as a substance that produced hydrogen ions (H+) as the only positive ion when dissolved in water or in an aqueous solution. it increases the concentration of hydrogen ions in an aqueous solution.
[tex]\begin{gathered} \text{According to Arrhenius} \\ HA_{(aq)}\rightleftarrows H^{+_{}}_{(aq)}+A^-_{(aq)} \end{gathered}[/tex]Bases are hydroxide compounds that give hydroxide ion (OH-) on dissociation in water. it increases the concentration of hydroxide ions in an aqueous solution.
[tex]\text{BOH}_{(aq)}\rightleftarrows B^+_{(aq)}+OH^-_{(aq)}[/tex]Arrhenius's definition of acid and base is still in use because it helps us to understand the acid-base properties of substances in an aqueous medium. neutralization, hydrolysis, and strength of acids and bases
