Have a little read: ... Finding the Concentration of Hydrochloric Acid by Titration Na2CO3 + 2HCl --> 2NaCl + H2O + CO2 The sodium carbonate in this solution is what we call the standard solution as it is the one which we know the concentration of accurately. This is because we have measured out an amount of sodium chloride (solid) to 1/100th gram, and then put this into a 100ml volumetric flask which was filled exactly to the 100ml mark. Mass of weighing boat: 0.87g Mass of weighing boat and sodium carbonate powder: 1.90g Mass of sodium carbonate powder: 1.03g Sodium chloride is neither deliquescent nor efflorescent. This means that it does not take in water from the atmosphere, nor does it give out water to the atmosphere. This means that the mass is purely sodium chloride and nothing else. Na2CO3 has a relative formula mass of 106g. I am using 1.03g which is 0.0097moles. When this is put in 100ml of water (0.1dm3) the
