3. A dry evaporating dish with a watch glass on it was weighed and the mass was recorded. About 25 milliliters of water was added to the mixture in the evaporating dish. The contents of the dish were stirred with a glass stirring rod... Ten milliliters of water was added to the evaporating dish, and the stirring and decanting was repeated. 4. Ring stand was set up. On the ring stand, the contents of the large evaporating dish were heated... After having been sufficiently heated to remove water, the dish was allowed to cool. The dish was then weighed and the mass was recorded. Data and result: Consult the page attached to the report Discussion: In this lab of Separation of the components of a mixture certain separation techniques were used and learned. In part B extraction was observed in separation of the water insoluble solid. The beaker from part A was used. Distilled water was added to the solid in beaker 2; it was then heated while being stirred occasionally for 5 minutes. The NaCl was said to dissolve leaving only the insoluble sea sand in beaker 2. Filtration was also observed in this experiment; first filter paper was folded and wetted then placed flat into a funnel. The funnel was placed into the apparatus for the gravity filtration. The remaining mixture found in beaker 1 was then poured into the gravity filtration apparatus and the filtrate was collected into the beaker. After that the funnel was removed and an additional amount of distilled water was put into beaker 1 and poured over the residue found in the funnel. The water was poured twice over the funnel. After all of the residue and filtrate was filtered the beaker was placed on a hotplate, the water boiled for a few minutes and the amount of liquid reduced quickly. The NaCl that was dissolved started to precipitate into a white solid. Once all of the liquid was gone the beaker was taken off the

hotplate to be cooled to room temperature. Once it was fully cooled the weight of the beaker containing now dry NaCl was taken. The mass of the recovered NaCl was determined by subtracting the mass of the empty beaker 2 and the mass of the beaker containing the dry NaCl.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
