Suppose you performed a titration of a weak acid and you found that the equivalence point occurred at 12.71 mL of added NaOH. At what volume would you use the pH to determine the pKa of the acid

The answer is a i think

The answer is bhope this

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
