The Gravimetric Analysis Lab will be carried out over two weeks and requires several trips to the lab:
A brief trip to place your samples in the drying oven.
A laboratory session to complete the precipitation of the Chloride Ion as Silver Chloride.
A brief trip to check for completeness of precipitation.
A laboratory session to filter the precipitated Silver Chloride and to start drying the precipitate.
A brief trip to weigh the precipitate.
Another brief trip to weigh the precipitate again.
For the Volumetric Analysis of Grape Must lab, you will need to dry your KHP standard and your unknown. This will take about one hour. You can do this in advance by stopping by the lab and placing these samples in the drying oven, then coming back an hour later and placing them in your desicator.
For the Volumetric Analysis of Butter lab, you will need to dry your Sodium Chloride and Unknown Chloride samples overnight. You will also need to dry your Silver Nitrate sample for one hour.
