Purpose: To effectively scale down the procedure of isolation Alum from 23 grams of Aluminum by means of gravity and vacuum filtrations. Once the Alum has been isolated the percent yield and melting point will be determined. Observations: -2.4 grams Aluminum combined with 67 milliliters 2 M KOH. This reactions causes fast bubbling around each of the aluminum strips. The bubbles are hydrogen gas. As the reaction proceeds the solution slowly becomes black in color. Some plastic residue is left behind -Filtration of the solution renders a clear liquid. Black residue and the plastic remain in the filter paper. -The addition of the initial volume of sulphuric acid causes white, fluffy precipitate to form. However the with the addition of the remainder of the sulphuric acid and stirring the precipitate dissolves, again leaving a clear liquid.

    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.
