Y12 Titration - Finding the value of x in Na2CO3xH2O - Demonstration






From 20to9.com. This is part 1. 4.0g of washing soda is dissolved in deionised water and made up to a total volume of 250cm3 in a volumetric flask. 25cm3 of this is titrated with 0.1M hydrochloric acid. In an accompanying vide-clip the results of this experiment are used to work out the value of x. Note, while washing soda has normally 10 moles of water of crystallization per mole of salt, it is possible for this to change when it is exposed to the atmosphere.
