Evaporation

We are learning about evaporation which basically is when water come to into the clouds when it gets drys. They are turning into a gas while they are doing this. 

Aim: To evaporate  copper sulfate to form a solute

Hypothesises: I think after we evaporate it it will turn to a dark blue solid

Equipment: Beacer, element, evaporation dish, copper solfate, heat proof mat, 

Method:
  1. Set up element

  2. Add 100mL of hot water to the beaker and place on the element.

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

  4. Carefully, place the 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 are forming. 

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


Observation :

When it started to get warmer some bubbles started to form, then after a while some condensation and steam started to form.

Conclusion:
The solids in copper sulfate couldn't evaporate so they just turned into crystals on the side of the dish, and the liquid just evaporated into air.
