Every step in this experiment has reasons behind its application. purr determines the masses of the crucible and barium chloride hydrate for obvious info collection and calculation purposed. The heating of the sample slowly for 10 minutes is done to remove the pee from the sample. A perennial mass for the sample must be obtained so accordingly it must be done slowly because if not you whitethorn loose mass from the sample. At the point where the crystalline substantial changes to a powdery solid the sample must cool and then have the mass taken of it. This process to repeated to obtain a uninterrupted mass. When one obtains a constant mass the water from the barium chloride hydrate has been completely removed. The anhydrous salt is placed in distilled water for filtering and bonding purposes. The 1.0M capital treat firmness of purpose is placed in with the distilled water and anhydrous salt so a chemical join reaction fire occur. The revo lutionary reply is heated to be sure that the chemical reaction is complete and all new bonds have been formed. The solvent is then filtered through the filter publisher to separate the accrue from the solution itself. This is done to separate the neglect from the solution so the mass of that may be obtained.
        My destruction based on this experiment is that the barium chloride hydrate was desiccate and then re-hydrated with distilled water. That solution was added to a solution of silver nitrate and then heated. A chemical reaction occurred that ca charter a precipitate to form in the solution and finalise at the bottom. This precipitate was most liable(pred icate) silver from the silver nitrate. This ! solution was then filtered to call for the precipitate by itself. The masses were obtained on the way and then used to calculate the moles of silver... If you want to get a full essay, severalise it on our website:
