Question

10. What is the Arrhenious definition for acids and bases? Why do we use thisdefinition?

Answer 1

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

Step-by-step 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.

`\begin{gathered} \text{According to Arrhenius} \\ HA_((aq))\rightleftarrows H^{+_{}}_((aq))+A^-_((aq)) \end{gathered}`

Bases are hydroxide compounds that give hydroxide ion (OH-) on dissociation in water. it increases the concentration of hydroxide ions in an aqueous solution.

`\text{BOH}_((aq))\rightleftarrows B^+_((aq))+OH^-_((aq))`

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
