2.10g of sodium hydrogencarbonate was dissolved in water and the solution made up to 250cm3. 25cm3 of this solution was pipetted into a conical flask and some methyl orange indicator added. The solution was neutralised by 25.9cm3 of dilute hydrochloric acid added from a burette. Calculate the concentration of the acid in g dm -3?
