Please read the forum rules (https://www.chemicalforums.com/index.php?topic=65859.0).

Besides, there is not enough information for anything more than "low, normal, high" type answer.

This is sometimes disclosed on the container. pH is a function of concentration (or more precisely, activity) so there is no way to figure this out without more information.

@switchyditchy There is no way to calculate correct pH without composition of powder and concentration of it's solution, but the pH will be alkaline (> 7).
