Question

30 mL of sodium carbonate solution is mixed with 20 mL of 0.8 N sulphuric acid. The resultant solution needed 20 mL of 0.7 N hydrochloric acid solution for complete neutralisation. Determine the strength of the sodium carbonate in gram per litre. (Take sodium carbonate to be anhydrous.)

Answer 1

Answer:

The specific gravity of sodium carbonate is 1.25 g/ml.

Explanation:

Hence the mass of 25 mL of solution of sodium carbonate is 1.25×25=31.25g.
