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.

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.
