In Kjeldahl's method, if the evolved ammonia is absorbed in of a standard acid of normality , what i — Practical Organic Chemistry and Purification Chemistry Question

💡 Solution & Explanation

1000 mL of 1 N acid neutralizes 1000 mL of 1 N $NH_3$, which corresponds to 17 g of $NH_3$ and contains exactly 14 g of nitrogen. Therefore, $V\ \text{mL}$ of $N$ normality acid corresponds to $\frac{14 \times N \times V}{1000}\ \text{g}$ of nitrogen.
