Which description is true of 0.02 m ca(oh)2 if ca(oh)2 completely dissociates in water? a. it’s a dilute strong acid. b. it’s a dilute strong base. c. it’s a dilute weak base. d. it’s a concentrated weak base. e. it’s a concentrated weak acid.

- B. It's a dilute strong base.

Explanations:- The given concentration of calcium hydroxide is 0.02 M which is low means it is diluted. It has hydroxide ions which means it's a base. If it dissociates completely then it's a strong base. The dissociation equation is written as:

So, the correct option is B) It's a dilute strong base.
