empirical formula for hydrated copper sulfate. In doing this lab‚ one was able to see the gradual change in the composition of a hydrate into an anhydrous salt. The lab was carried out with numerous steps. First‚ one had to safely prepare by putting on goggles. One then had to wash and heat the dish with the flame for about three minutes. After allowing the dish to cool‚ one had to weigh the evaporating dish and record the weight. Two to three grams of copper sulfate hydrate was then added to the dish and

Separation of a Mixture Do-Your-Own-Lab What you will need to do: 1. Create a flow chart for the separation of your unknown mixture – BERFORE doing lab 2. Create data table – BEFORE doing lab 3. Do lab 4. Analyze data – calculate percent composition of your unknown mixture = 15 points = 30% 5. Write a complete lab report = 35 points = 70% 1. A flow chart is often used to illustrate the steps involved in the separation of a mixture. Flow charts are constructed BEFORE

In this lab‚ we will be analyzing alum by doing three different tests. The first will be to find the melting point‚ the second to find the amount of water in alum‚ and the third is to find the percent sulfate. We expect the values to be close to the actual.
