Question

1.To determine the rate constant of saponification reaction of ethyl acetate.
For calculation use the following observations:
Titration between NaOH & HCl
S.No. Volume of 0.02N HCl Burette reading Titrate value
Initial Final (T)
1 20.0 ml 0.0 ml 19.9 ml 19.8 ml
2 20.0 ml 0.0 ml 19.8 ml
3 20.0 ml 0.0 ml 19.8 ml
Titration between ( NaOH + HCl ) & NaOH
S.No. Volume of HCl +
NaOH
Burette reading Titrate value
Initial Final (T0)
2 20.0 ml + 10.0 ml 0.0 ml 9.9 ml 9.8 ml
20.0 ml + 10.0 ml 0.0 ml 9.8 ml
3 20.0 ml + 10.0 ml 0.0 ml 9.8 ml
A 20.0ml of reaction mixture ( 100.0 ml,0.02 M Ethyl acetate + 100.0 ml,
0.02M NaOH ) when titrated against 0.02M NaOH solution at different
time intervals gave the following results :
Time (min) 0 5 15 30 50 75
Titrate Value
(Tt)
12.6 13.6 16.0 17.2 18.5 19.2
