Question

Match the point during an acid-base titration with the description of how the pH would be determined at that point.

1.) After titrant is added but before the equivalence point 2.)At the equivalence point 3.)After the equivalence point 4.) Before titrant is added
Match with: A.)pH of salt formed during the reaction B.)pH with excess titrant C.)pH with original concentration of analyte D.)pH of remaining analyte

Answer 1

(2) At equivalance point pH = salt formed in the reaction.(B)

(1) Before equivalance point, titrant will fully consumed and analyte is in excess . So pH is pH of remaining analyte . (D)

(3) After equivalance point, titrant is in excess and analyte is fully consumed. So, pH with excess titrant (B)

(4) Before titrant is added, pH is the pH of original concentration of analyte (C)
