Question

calculate the pH value of 0.005 M NaOH.2​

Answer 1

Answer:

NaOH.2 is not base

pH of NaOH

Here, the molarity of the solution is 0.05M.

That means,every 1 litre solution has 0.05 M NaOH in it.

Further, the dissociation is practically 100%.

=> pH = 14 - pOH = 14 - 1.30102999566 = 12.699 (approx.)
