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

10 ml of 1 M `H_(2)SO_(4)` = 20 ml of M `NH_(3)`
1000 ml or 1M ammonia contains 14g nitrogen
20 Ml of 1M ammonia contains `(14 xx 20)/(1000) g N_(2)` % of nitrogen ` = (14 xx 20 xx 100)/(1000 xx 0.5) = 56.0`
