... process of gravimetric analysis. Theory: The Chloride in the unknown salt is precipitated by the reaction of Chloride ions with Silver ions producing Silver Chloride which is insoluble in water making it possible to collect it as a precipitate later on through ... and cause the analytical results to be low. None the less if this photochemical decomposition happens in the presence of excess Silver ions in an aqueous solution the following additional reaction occurs: 3Cl2(g) + 3H20(l) + 5Ag+(aq) ï‚® 5AgCl(s) + CIO3-(aq) + ... 6H+(aq) If the above reaction happens then the analytical ...

... digestion is finished, the solution is filtered; in this experiment filter paper was used. Then deionized water or dilute acids are used to wash the precipitate to ensure that all aqueous ions are removed from the surface of the precipitate. The precipitate is then dried until a constant weight is obtained which ensure that there is no remaining water in the precipitate. Then ... was probably that the barium sulfate still had water molecules in it and it was not given enough time to dry. There also is the possibility that there were still ions that did not get rinsed off in the step of ...
