What is the pH number of sodium hydroxide?

Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.


Does sodium hydroxide have pH 7?

No, sodium hydroxide (NaOH) does not have a pH of 7. Sodium hydroxide is a strong base and has a pH greater than 7. The pH of a solution of sodium hydroxide depends on its concentration. A 0.1 M solution of NaOH has a pH of 13.

What is sodium hydroxide pH level?

pH level is a measure of acidity, the simplest way to understand it is the lower the pH value the more acid something is, and the higher the pH value the more alkali something is. Finaly a value of pH 7 is neutral (neither acid or alkali).pH does not show the amount of Sodium Hydroxide present, however the pH would increase if Sodium Hydroxide was added because Sodium Hydroxide is alkali.The pH of concentrated (1 M) Sodium Hydroxide is 14.
