The equivalence point of any acid titrated with a base occurs when the
A. concentration of the acid and concentration of the titrant are equal.
B. mass of the acid and the mass of the titrant are equal.
C. pH of the mixture of the acid and titrant is 7.0.
D. volume of the acid and the volume of the titrant are equal.

Hi I got A, but I'm second greeting myself with C, can you pleas look at this equation and tell me which answer is correct thank you

1. C can't be right since the equivalence point for some acid/base titrations is <7 (NH3 and HCl as an example) and some are >7 (NaOH and acetic acid as an example.) Of course you know B and D can't be right. Which leaves only A.
