Question

A substance that produces hydroxide ions when placed in water is a(n) _____.

Answer 1

Answer: A substance that produces hydroxide ions when placed in water is base.

Explanation:

Bases are the substance:

• Which gives negatively charged hydroxide($OH^-$) ions in aqueous solution.

• Which have pH value ranging from 7 to 14.

• $BOH(aq)\rightarrow B^+(aq)+OH^-(aq)$

Where as acid gives positively charged hydronium ion($H^+$) in aqueous solution.

Answer 2

A substance that produces hydroxide ions when placed in water is a base. When a base is dissolved in water, the molecule will form into ions and bases produce OH- ions. Meanwhile, acids produce H+ in water.
