What is the PH of 0.00 1 moldm33 solution of the sodium hydroxideA. 14B. 13C. 12D. 11

The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution.

However, in the case of sodium hydroxide (NaOH), it is a strong base, meaning it dissociates completely in water to form Na+ and OH- ions. The concentration of OH- ions, not H+ ions, is given.

We can find the pOH of the solution first, and then use the fact that pH + pOH = 14 (at 25 degrees Celsius) to find the pH.

The pOH is calculated similarly to pH, but with [OH-] instead of [H+]: pOH = -log[OH-].

Given that the concentration of the sodium hydroxide solution is 0.001 M, the pOH of the solution is -log(0.001) = 3.

Therefore, the pH of the solution is 14 - pOH = 14 - 3 = 11.

So, the correct answer is D. 11.
