Question

carrie is conducting an experiment on a solution. the solutions initial ph is 3.2. then, as carrie gradually adds compound x into the solution, the ph increases to 9.8. which is the most likely identity of compound x? a. a strong acid, such as hydrochloric acid (hcl) b. a strong base such as sodium hydroxide (naoh)

Explanation:

Acids lower pH and bases raise pH. Since the pH increased from 3.2 to 9.8, a strong base was added.

Answer:

B. a strong base such as sodium hydroxide (NaOH)
