Edward Phillips Chem1045L Frank Brown Lab Investigation 3- What is the identity of the unknown hydrate? During this investigation, the goal our group was trying to achieve was to determine the identity of the unknown hydrate. A hydrate is a pure substance because it contains water molecules embedded in its crystal structure that do not vary. The hydrate at first sight will appear dry but when heated water molecules are released thus causing the total mass of the hydrate to decrease. After the water molecules have been released the solid that is left behind is called the anhydrous. The percent of water in the hydrate can be found out and with this information we can then figure out what is the identity of the unknown hydrate. To find the percent of water in the hydrate you would first gather the ratio of the mass of water lost after heating with the Bunsen burner and then you would divide that ratio by the mass of the original hydrate you started off with before the heating process. Within this experiment we used the Law of constant

    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.
