Explain naoh was required to back titrate the excess hcl

Reference no: EM13650291

The mixing of barium chloride solution with sodium carbonate solution resulted in a white precipitate. 25.00 ml of 0.3000 M HCl was added to 0.250 g of the solid with resultant fizzing and dissolving of the sample. 24.80 ml of 0.2000 M NaOH was required to back titrate the excess HCl. What was the calculated molecular mass of the product and how likely is it that the product was barium carbonate?
