To solve the problem, we will follow these steps: ### Step 1: Calculate the amount of unused H2SO4 We know that 60 ml of \( \frac{N}{5} \) H2SO4 was used to absorb the ammonia, and 40 ml of \( \frac{N}{10} \) NaOH was used for neutralization. Using the neutralization reaction: \[ \text{H}_2\text{SO}_4 + 2 \text{NaOH} \rightarrow \text{Na}_2\text{SO}_4 + 2 \text{H}_2\text{O} ...

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 M H_(2)SO_(4) . The residual acid required 60 mL of 0.5 M solution of NaOH for neutralization. Find the percentage composition of nitrogen in the compound. Strategy: Step 1 . Convert molarity into normality using the relation Normality (N) = n xx Molarity (M) where n factor is either the acidity of base or basicity of acid. Step 2 . Calculate the milliequivalents of NaOH which is equal to the milliequivalents of unreacted H_(2)SO_(4) . Step 3 . Calculate the milliequivalents of total H_(2)SO_(4) and subtract the milliequivalents of unreacted H_(2)SO_(4) to get the milliequivalents of NH_(3) evolved. Step 4 . Calculate the equivalents of NH_(3) , moles of NH_(3) , and moles of N . Step 5 . Calculate the mass of N in the organic compound. Step 6 . Finally, calculate % of N or directly apply Eq. (13.8) or (13.9) to get the % of N in the organic compound.
