acid
and concentrated acid
(b.) 25cm3 portions of 0.10mol
dm-3
solution of sodium
trioxocarbonate
(iv)
were titrated against dilute
hydrochloria acid.
THE TABLE BELOW GIVES THE
BURRETE READINGS final burette
reading (cm3) first titration was
25.60
second was 30.85 third was
26.35
initial reading first was 085
second
was 5.65 third was 1.50
(1.)name a
suitable indicator for d titration n
give
its color change at d end point

determine d conc of d acid in
mold
per
dm3. (iii) state 3 precautions to
ensure
dat accurate result are obtain 4 d
