Science: Making salt
Aim: To produce chloride salt by carrying out a neutralisation reaction.
Equipment: *Not ours*
Equipment: *Not ours*
- Copper Oxide Powder
- Dilute Sulfuric acid, 50mL
- Measuring Cylinder
- Two 100 mL beakers
- Bunsen burner
- Tripod
- Gauze mat
- Funnel
- Filter paper
- Thermometer
- Spatula
- Evaporating Bunsen
- Stirring rod
Method
- Add 20mL of sulfuric acid to a 100Ml beaker. Heat the acid until it reaches 70 degrees. Turn off you Bunsen.
- Once heated, use a spatula to add pea sized portions of copper oxide to the beaker. Stir the mixture for 30 seconds
- Repeat the step ahead until no more dissolves. Allow the beaker to cool.
- Fold the filter paper and place it in the funnel. PLace the filter funnel into the second beaker.
- Make sure the beaker is cool enough to hold at the top. The contents should still be hot.
- Gently swirl the contents of the beaker to mix, and then pour into the filter paper in the funnel. Allow to filter through.
- Rinse the beaker you used to heat the mixture previously, and place it back on top of your tripod filled with 50-60 mL of water
-Place the evaporating basin on top of the beaker and carefully pour some of the solution from the beaker into the evaporating basin.
-Gently heat the beaker until the solution in the evaporating basin had reduced by half.
- Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warm place where it will not be disturbed and observe over the next few days. Blue copper sulfate crystals should form.
Observation:
The copper oxide was a black powder once putting it in copper oxide into the sulfuric acid it changed colors into a nice blue.
Result:
At the end of the experiment it didn't work to well there were only a few crystals around the side and one in the middle. I did this experiment last year and I feel like I did it better than.
Discussion:
This experiment was fun but I feel like it would of done better if I took my time. My group kind just rushed it and it didn't turn out to well. Last year I was able to get more crystals and they looked cleaner and better.
Conclusion:
The experiment was pretty fun we got to see crystals form but I think it would of been better taking our time. Apart from the I love the chemical reaction that happen, Its pretty fascinating to see. Its also a lot of fun to do as well.
