Hidroxyde

5. Step

6. Result Data
A. Oksalat acid mass
: 1,576 gram
Solution volume
:250 ml
Oksalat acid molarity
: 0,05 M
B. Oksalat acid volume
: 10 ml
NaOH volume (1)
: 10,4 ml
NaOH volume (2)
: 10,1 ml
NaOH average volume : 10,25 ml

7. Data Analysis

Oksalat Acid molarity = m x 1000
Mr
V
= 1,576 x 1000
126,07 250
= 0,05
Oksalat acid normality = a x M
= 2 x 0, 05
= 0,1

8.  H2C2O4 (oksalat
acid) and NaOH normality
H2C2O4
=
NaOH
V1.N1
=
V2.N2
10. 0,1
=
10,25 . N2
=
0,097 (NaOH)
N2

9. Conclution
 From
the experiment , we get the
normality of NaOH is 0,097
