Question 4 • Foothill-B Period-Chemistry-26/27B

Consider this reaction: Which statement is most likely true about KOH?

Answer
A
It turns blue litmus red.
B
It turns clear phenolphthalein pink.
C
It reacts with metals to form hydrogen gas.

Explanation

KOH (potassium hydroxide) is a strong base. Bases turn clear phenolphthalein pink, so statement B is true. A is false because bases turn red litmus blue, not blue litmus red; reacting with metals to produce hydrogen is more characteristic of acids.
