Stoichiometric Point

Postby Daniel Yu 1E » Sat Dec 07, 2019 1:39 pm

How can a solution with equal acidic and basic properties have a pH unequal to 7? Like we went over in lecture, how come some stoichiometric / equivalence points don't have a neutral pH?

Not entirely sure what the question is asking, as the stoichiometric point is when there is an equal number of moles of acid and base in a solution, which by definition means it is neutral. If the moles of acid equal the moles of base, the solution has a pH of 7.

the equivalence point is the point at which chemically equivalent quantities of reactants have been mixed however this could mean equal quantities of a strong acid and weak base it d9esnt indicate what reactants are being used
