A) salt

B) acid

C) base

Answer:

A substance that yields a cation plus the hydroxyl ion in water is a (n) base.

Explanation:

Base is a substance that "donates electrons, accept protons, or releases hydroxide (OH-) ions" in aqueous solution. When a base is dissolved in water, it dissociates to give hydroxyl ions. Hydroxyl ion which is a negatively charged molecule and having one oxygen bonded to one hydrogen. In case of the base particles, when comes in contact with water becomes slippery as well as changes its colour. For bases, the pH value ranges from 8-14.
