In the Kjeldahl's method for estimation of nitrogen present in a soil sample, ammonia avolved from 0.75 g of sample neutralized 10 mL of 1 M `H_(2)SO_(4)`. The percentage of nitrogen in the soil is

Text Solution

Verified by Experts

The correct Answer is:
37.33
`%N `=(1.4 xx "Volume" xx "Molarity" xx "Basicity of acid")/("Weight of the substanc taken")`
` = (1.4 xx 10 xx 1 xx 2)/(0.75) = 37.33`.
