Aim
Our aim is to make salt and water from copper oxide with an acid
Equipment
Copper oxide powder, dilute sulfuric acid, 50ml measuring cylinder, two 100ml beakers, bunsen burner, tripod, gauze mat, funnel, filter paper, thermometer, spatula, evaporating basin, stirring rod.
Method
1 Add at least 20ml of sulfuric acid to a 100ml beaker, then heat it on the heat plate, until it reaches 70C, then turn your beaker off
2 Then use a spatula to add pea-sized portions of copper oxide to the beaker, stir for 30-40 seconds
3 Repeat the previous step until no more will dissolve, wait for the beaker to cool down.
4 Fold the filter paper and place it into the funnel, place the filter funnel tunnel into the second beaker.
5 Make sure the beaker is cool enough to place on top, and the contents should be hot.
6 Gently swirl the contents of the beaker to mix. then pour the paper filter into the funnel.
7 Rinse the beaker, then place it back on top of the tripod filled with 50-60ml of water.
8 Place the evaporating basin on top of the beaker and pour some of the solution from the beaker into the evaporating basin.
9 Gently heat the beaker until the solution have reduced by half
10 Leave the evaporating basin to cool. once it has cooled down, move the basin to a warm place, and observe it for the next couple of days.
