In science yesterday we made copper sulfate crystals. Here is the method we used
1. Add 20 ml of sulfuric acid, into a 100 ml beaker. heat the acid to 70o c. Turn off the Bunsen burner
2. once heated, use a spatula to add pee-size portions of copper oxide. to the beaker. stir for 30 seconds.
3. repeat step two, till no more will devolve. allow beaker to cool
4. fold the filter paper and place it into the funnel. place the funnel into the second beaker.
5. make sure the beaker is cool enough to hold the top. the contents should still be hot.
6. gently swirl the contents of the beaker to mix, and then poor into the filter paper in the funnel. allow to filter though
7. rinse your beaker you used to heat up the mixture previously, and place it back on tripod filled with 50-60 ml of water
8. place the evaporating basin on top of the beaker and carefully poor some solution from the beaker into the basin.
9. gently heat the beaker until the solution is reduced by half.
10. leave the evaporating basin to cool. once cool, move to the evaporating basin to a warm place where it will not be disturbed. observe for the next few days, blue copper sulfate should form
