Question

Which of these is a strong base?
a) Be(OH)₂
b) Ba(OH)₂
c) NH₄OH
d) Zn(OH)₂

Answer 1

The correct answer is b) Ba(OH)₂. Ba(OH)₂ is a strong base because it dissociates completely into ions when dissolved in water.

Step-by-step explanation:

The correct answer is b) Ba(OH)₂. Ba(OH)₂ is a strong base because it dissociates completely into ions when dissolved in water.

This means that it releases hydroxide ions (OH-) into the solution, resulting in a high concentration of hydroxide ions. In contrast, the other compounds listed are weak bases because they only partially dissociate into ions when dissolved in water.
