Hurumanu - Evaporation Experiment

Aim:  We are trying to evaporate to separate our mixture which is separating liquid and solid; We are trying to remove the liquid part, to end up with something solid.

Hypothesis:
 I think that the copper sulfate (liquid) will turn into crystals since the copper sulfate is blue,
the crystals will be blue.

At the end of our experiment, there won't be much water left since the water had been turned into gas and the steam went through the hole of the beaker even though there's a basin on top of it.


Equipment: 

• Copper Sulfate Solution
• 250mL Beaker
• Heatproof mat
• Evaporation basin
• Water
• Bunsen burner/stove (heat, element)

Method: 

1.  Set up the bunsen burner/stove.
2. Add 50mL of water to the beaker and place it on the bunsen burner/stove.
3. Add copper sulfate on the evaporation basin.
4. Carefully place the evaporating basin on top of the beaker which has water.
5. Turn the bunsen burner/stove to 8.
6. Heat the solution until most of the solvent has been evaporated and crystals of solute forming.
7. Turn off the heat - careful not to touch the equipment as it will be hot for a long time.

Observation:

What I see: The water was boiling and as we observe more, the lesser water there is and the copper sulfate was slowly turning into crystals, there were also steam.

What I hear: I hear the water boiling

What I smell: It smells weird

Conclusion: 
In the end, the only a small part of the copper sulfate turned solid, there was less water, the rest evaporated.

Discussion: 
 In this experiment, we were trying to evaporate the water for it to steam and heat up the copper sulfate in order to turn it into crystals.

Evaluation:
 I think our experiment was in the middle, some of it turned to liquid but it would've been better if all the copper sulfate turned into crystals. I was really looking forward to that experiment since we've never done that kind of experiment before especially that it will turn to crystals and crystals fascinates me.
