Question

Acidity for Na2CO3 for determining the equivalent weight in titration practicals

Answer 1

Answer:

The Na2CO3 content of the given sample is determined by titration against standard hydrochloric acid using methyl orange as indicator: Na2CO3 + 2HCl = 2NaCl + H2O + CO2. The equivalent weight of Na2CO3 is half its molecular weight (M). This means M/2 g of Na2CO3 is equivalent to 1000 ml of 1 N HCl.
