Answer to Question #256875 in General Chemistry for indu

Question

(b) Consider the titration of 0.10 mol dm'3 CHICOOH (K,:1.8x10-5 and

K,: 1.0x10-ra at 25 oC) with 25.0 cm3 of 0.10 mol dm-3 NaOH. (for{utt credit, all

relevant equations must be shown)

i Calculate the main points {at leastfour points) needed to plot the titration curve.

ii Sketch the expected titration curye highlighting the points you determined in (i).

;

iii If a student obtained an end point of 24.80 cm3 for the above titration, d#rmine

the titration enor.

Answer 1

0.1×1.8×10^-5= 0.000018

1×10^-1×25=2.5
