Question

What is a base?
A. a substance that can donate an H+ ion

B. a substance that has a low pH value

C. a substance that is alkaline

D.a substance that can accept an OH– ion

Answer 1

I’m sorry if it’s wrong but I think its D

Answer 2

Answer:

C. a substance that is alkaline

Explanation:

Alkaline substances are basic substances. Like all basic substances, alkaline substances have a high pH, above 7, in addition to mandatory release of the OH- anion in aqueous solutions.

Accordingly, we can say that it is incorrect to say that the bases can release the H + cation, or that it is a substance that has a low pH, or that it is a substance that receives the H + cation.
