What is the pH of a 0.0300 M NaOH (strong base) solution?

A. -7.88
B. 0.5
C. 12.477
D. 1.55
E. None of the above

Answer :

Final answer:

The pH of a 0.0300 M NaOH (strong base) solution is approximately 1.522.

Explanation:

The pH of a solution is a measure of its acidity or alkalinity. In this case, we have a 0.0300 M NaOH solution, which is a strong base. NaOH is a strong base because it completely dissociates in water to produce hydroxide ions (OH-).

To calculate the pH of a NaOH solution, we can use the equation: pH = -log[OH-].

Since the concentration of NaOH is 0.0300 M, the concentration of hydroxide ions (OH-) is also 0.0300 M.

Plugging this value into the equation, we get: pH = -log(0.0300) = 1.522.

Therefore, the pH of a 0.0300 M NaOH solution is approximately 1.522.
