Is pH normally taken at equilibrium concentrations?

If the question gives you a pH of a solution with a certain initial molarity, could you imply that the [H+] you calculate from it is its equilibrium [H+] concentration?

I think yes, if it doesn't say anything like "the starting or initial pH was...", you can assume it is at equilibrium.

i think the problem will specify if the pH is at the initial or equilibrium state of the solution, because you could put that H+ concentration at either point when making your ICE table

Usually it should tell you if it isn't taken at equilibrium. This really isn't a big problem, just make sure you put the H+ concentration in the correct place in the ice tables.

If not given specifics, then it's safe to assume that it's at equilibrium.

I think if not asked for it directly in the question, it's safe to assume its at equilibrium.

If you do not see anything stating otherwise, it is safe to assume the system is at equilibrium.
