Which of the following is correctly identified?

Question

Quizplus · Accepted Answer

NaOH is a strong base because it dissociates completely into ions in water, producing a high concentration of hydroxide ions (OH-) in solution. A strong base is defined as a base that completely dissociates into its ions in water.

Answer: C
 HCl is a strong acid because it dissociates completely into ions in water, producing a high concentration of hydronium ions (H3O+) in solution. A strong acid is defined as an acid that completely dissociates into its ions in water.

Answer: E
 Ca(OH)2 is a strong base because it dissociates completely into ions in water, producing a high concentration of hydroxide ions (OH-) in solution. However, the compound listed is just "Ca," which is not an acid or base on its own.

Therefore, the correct choice is B only: NaOH is a strong base, while C is incorrect because HCl is a strong acid and E is incorrect because the compound listed is not an acid or base on its own.
