Crystals experiment 🕯

Aim: To find out how to form crystals with chemicals.

Equipment:
Copper oxide power
Sulfuric acid
50mL measuring cylinder
Two 100mL beakers
Bunsen burner
Tripod
Gauze mat
Funnel
Filter paper
Spatula
Evaporating basin
Stirring rod





Method:

1. Add sulfuric acid (20 ml) to the 100 ml beaker, heat until near boil. After that, make sure that the bunsen burner is off so you don't burn anyone or anything.

1.  After that, use a Spatula and add ( about the tip of the Spatula) copper oxide. 

1. Stir the solution for approximately 30 seconds.

1. Continue to add copper oxide until it dissolves no more.

1. fold the filter paper in half and then in half again and then place it in the funnel. add to the other beaker.

1. Let the solution to cool down enough so you can carry the baker by the top. The solution MUST be hot still.

1. Swirl the solution until all is mixed, then pour the liquid into the funnel with the filter paper in it. Let the solution filter through until there is no liquid left in the funnel. All liquid should be in the beaker.

1. Rince the beaker that was used to boil the solution and fill the beaker with 50-60 ml of water.

1. Turn the bunsen burner back on and place the water on the tripod and then place the evaporating basin on top of the beaker. Pour the liquid into the evaporating basin.

1. Either the water or the solution needs to evaporate till half way then turn the bunsen burner off and wait for the evaporating basin to cool down.

1. Once cooled down a move to a place where it would not be disturbed.

1. Over the next few days blue, shiny crystals should appear.

Results: 
Our crystals had a white powder-like substance on top as it was over boiled. They still look alright.

Discussion:
 This takes about two hours to complete but it was fun. If I ever did this again, I would make sure it did not over boil.
