Answer : The correct option is A substance that increases \(OH^-\) concentration when it is dissolved in water.
Explanation :
Arrhenius Definitions :
- Arrhenius Acid : It increases the concentration of hydronium ion \((H_3O^+)\) in an aqueous solution. In other words, a substance dissociates in water to form \(H^+\) ion.
- Arrhenius Base : It increases the concentration of hydroxide ion \((OH^-)\) in an aqueous solution. In other words, a substance dissociates in water to form \(OH^-\) ion.
