Consider the titration of 40.0 ml of 0.400 m hi by 0.300 m naoh. calculate the ph after 41.1 ml of naoh has been added. ph = 1.34 hint: determine the major species present after the strong base (naoh) reacts completely with the acid, then calculate the ph. you are correct. your receipt no. is 157-9569 : receipt previous tries at what volume (in ml) of naoh added does the ph of the resulting solution equal 7.00? include the units of ml in your answer.
