Question

What is the Arrhenius definition of a base? A substance that increases H3O+ concentration when it is dissolved in water. A substance that increases OH– concentration when it is dissolved in water. A compound that donates protons. A compound that accepts protons

Answer 1

b

Step-by-step explanation:

Answer 2

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.
