In an experiment to analyze mixture of sodium carbonate, Ask an Expert

Academics

In an experiment to analyze mixture of sodium carbonate, sodium bicarbonate, and an inert component. 10.00ml of 0.100M HCl were used to titrate 0.300g of the sample using phenolphthalein as the indicator. Calculate the number of moles and the mass of sodium carbonate present in the mixture. (Formula weight of sodium carbonate is 106g/mol)

Also if you want to continue. To finish the analysis, drops of methyl orange indicator were added to the solution in problem 4 and the titration was continued with the 0.100M HCl. A total of 30.00mL of HCl were used to reach the end point.

a. Calculate the number of moles of sodium bicarbonate originally present in the unknown mixture, knowing that 20.0mL of 0.100M HCl were used in the step 2 of the titration, using methyl orange as an indicator.

b.Calculate teh weight percent of sodium carbonate, sodium bicarbonate and the inert component in the samples.(Formula weight of sodium bicarbonate = 84 g/mole)
