What is the difference between the endpoint and the equivalence point of a titration?   A. The endpoint cannot be seen, the equivalence point requires an indicator B. The equivalence point is the halfway point of the titration, the endpoint is the end of the titration. C. The endpoint is halfway through the titration and the equivalence point is the end of the titration. D. The endpoint is when a color change occurs due to the addition of an indicator that indicates the equivalence point has been reached.

A 25.0 mL sample of a saturated calcium hydroxide solution is titrated with 0.023 M HCl and the equivalence point is reached after 38.0 mL of titrant are dispensed. What is the concentrationof the hydroxide ion?

Consider Titration of 25 mL of .1 M CH3CO2H With .1 M NaOH. Calculate The pH After Adding The Following Volumes of NaOH: a. 0 mL b. 12.5 mL. c. 20 mL d. 25 mL. e. 37.5 mL. I do know the answers, I just don't know the way to get to these answers. a. pH = 2.87 b. pH = 4.74 c. pH = 5.34 d. pH = 8.72 e.  pOH = -log(.0192 M) = 1.72 pOH 14-1.72 = 12.28 pH (I just know the last steps to  the answer for part e, but don't know all the other steps to get to answer).
