Answer

Explanation:

Step1: Recall pH of pure water

Pure water is neutral and has a pH of 7.

Step2: Understand the nature of sodium hydroxide

Sodium hydroxide ($NaOH$) is a strong base. When added to water, it will increase the pH of the solution. A basic solution has a pH greater than 7.

Answer:

before = 7, after = 9
