A sample of 0.50 g of an organic compound was treated according to Kjeldahl's method. The ammonia evolved was absorbed in 50 mL of \(0.5 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4\). The residual acid required 60 mL of 0.5 M solution of NaOH for neutralisation. The percentage of nitrogen in the compound is
- A 25
- B 30
- C 28
- D 56
Answer & Solution
Correct Answer
(D) 56
Step-by-step Solution
Detailed explanation
Volume of acid taken \(=50 \mathrm{~mL}\) of \(0.5 \mathrm{MH}_2 \mathrm{SO}_4\) \(=25 \mathrm{~mL} \text { of } 1 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4\) Volume of alkali used for neutralisation of excess acid. \(=60 \mathrm{~mL}\) of…
