Evaporating Experiment

 

    

Aim-Separating the copper sulfate and the water then to make it to a solid

Hypothesis-I think that the copper sulfate and the boiled water when mixed the two liquids will combine together and become into a clear blue solid.

Method:

1. Set up element.

2.Add mL of hot water to the beaker and place element.

3.Add copper sulfate to the evaporating basin until it is quarter full.

4. Carefully, Place the evaporating basin on top of the beaker.

5. Turn on the element to 3.

6. Heat the solution until most of the solvent has been evaporated and crystals of solute form.

7.Turn off the element- be careful not to touch, as it will be hot for a long time

Observations:When the water  began to boil the copper sulfate began to sort of become a solid sticking to the edges.

Conclusion:Now it has turned into a Crystal type of looking that's stuck around the whole socket of the tube

Discussion:The copper sulfate began to turn into a crystal  

Evaluation:The crystal shaped solid inside the tube became solid and stuck on the out skirts of the tube and had solidified that copper sulfate.

Dilution Experiment

 What is dilution?

Dilution is the addition of solvent, which decreases the concentration of the solute in the solution. Concentration is the removal of solvent, which increases the concentration of the solute in the solution.

Most dilute is when their are less particles which means less ingredients mixed with the liquid.

Less concentrated is also the same as most dilute, It is when their are less particles.

My hypothesis-

Which test tube is the most dilute? 

The sixth tube will be the most dilute because of the most liquid has been added to that one so I'm guessing it'll be six.

Which test will be least dilute?

The first because that was the one that had the most particles in it and then removed but it still had the most.   

My hypothesis was incorrect the most dilute was the first because I added the potassium permanganate in the sixth tube which had the most colour and added 5mL of the liquid from the sixth and the colour dyed down to a less concentrated colour which ended on the first.



Filtration Experiment

 Hypothesis-

My hypothesis is that I think it will mix the two liquids and turn colours into a different colour and then have a chemical reaction and could cause a blob of froth on the top.=What will happen when we filtrate the mixture-I think that the particles will split apart and form a different type of liquid

Equipment:

Sodium Carbonate

Conical flask

Stirring Rod

200mL

Funnel

Filter paper

Results-When mixing the Copper Sulfate & Sodium Carbonate the sodium carbonate caused it to create blobs inside the beaker and when we filtrated it in separated the Copper Sulfate from the Sodium and turned it into Sodium it self.I reckon it caused that to happen because of the filter made the blobs of copper separate from it's natural form at first when mixed and because of the filter it caused the blobs to be held inside funnel with the filter.
