Science Making Salts

Aim: To produce copper sulfate salt by reacting copper oxide with an acid.

Equipment: Copper oxide, sulfuric acid, beaker, conical flask, bunsen burner, tripod, gauze mat, funnel, filter paper, spatula,

Method:

  1. First, we heated the sulfuric acid on the bunsen burner after heating it enough to about 70c we started mixing in the copper oxide with the sulfuric acid.
  2.  After mixing the sulfuric acid with the copper oxide it turned into a blue colour then filtered the blue solution, We did this to make the blue liquid high concentration.
  3.  After filtering the blue liquid we use a water bath to evaporate the blue solution.
  4. Lastly, we placed the blue liquid next to the window on the window sill to crystalise the liquid.

 

Results:

After two days of waiting, we came back today and saw that our blue liquid had turned into a lot of tiny straight little crystals.

Our Crystals after two days:

Equations:

Symbol Equation: CuO + H2SO4  > CuSO4 + H2O

Word Equation: Copper oxide + Sulfuric acid   > Copper Sulfate + Water
