The ammonia evolved from the treatment of 0.30 g of an organic compound for the estimation of nitrogen was passed into 100 mL of 0.1 M H₂SO₄. The excess acid required 20 mL of 0.5 M NaOH solution for complete neutralisation. The organic compound is

Answer: (C)

Solution

Total meq H⁺ (diprotic acid) = 100 × 0.1 × 2 = 20 meq. meq NaOH used on excess acid = 20 × 0.5 = 10 meq. meq H⁺ reacted with NH₃ = 20 − 10 = 10 meq = mmol N. Mass N = 10 ×
