Q. In Kjeldahl's method for the estimation of nitrogen, the formula used is
Organic Chemistry – Some Basic Principles and Techniques
A
$\%$ of $N =\frac{1.4 VW }{N}$
12%
B
$\%$ of $N =\frac{1.4 VN }{W}$
69%
C
$\%$ of $N =\frac{V N W}{1.8}$
9%
D
$\%$ of $N =\frac{1.4 WN }{V}$
10%
Solution:
The nitrogen is estimated in Kjeldahl’s method by the following form ula:
$\% \text { of } N =\frac{1.4 NV }{W}$
where, $V=$ volume of the acid used, $N=$ normality of the standard acid, $W=$ weight of the organic compound.
