Question

Which of the following ions is formed when a base is dissolved in a solution?

H+
O−
OH−
SO42+

Answer 1

Answer: OH-

Explanation: I took the test

Answer 2

`\huge\boxed{\sf OH-}`

Step-by-step explanation:

According to Arrhenius concept of acid and base:

"When a base in a solution, produces/yields OH- (Hydroxide) ions."

So, when a base is dissolved in a solution, it produces OH- ions.

For example:

NaOH ⇄ Na⁺ + OH⁻ (So, it is a base)

`\rule[225]{225}{2}`

Hope this helped!
