Question

select the correct answer.
what occurs when there are oh⁻ ions in a solution?
a. a sour taste
b. a reaction with al₍ₛ₎ to release hydrogen gas
c. a slippery feeling
d. a reaction with a base

Explanation:

• Option A: Sour taste is a property of acids (containing \(H^+\) ions), not bases with \(OH^-\) ions. Eliminate A.
• Option B: Metals like Al react with acids (to release \(H_2\)), not typically with basic solutions (containing \(OH^-\)) to release \(H_2\). Eliminate B.
• Option C: Basic solutions (with \(OH^-\) ions) feel slippery, which is a characteristic property of bases.
• Option D: A base cannot react with another base in a typical acid - base reaction (acids react with bases). Eliminate D.

Answer:

C. a slippery feeling
