Growing cyrstals

Aim: 
I want to find how to make crystals form into a super-saturated solution
Equipment:

  • a supersaturated solution sodium acetate 
  • a seed crystal of sodium acetate
  • Bunsen burner
  • Boiling tube
  • Scissor Tongs
  • Heat Mat
  • Funnel
  • Filter paper
  • Small beaker

Method:
































 I took a super saturated solution and we put it into a boiling tube and funnel and we watch it slowly drip down and it seed Crystal in the boilling tube and it stared to Crystal's

Dilution

Aim:
I want to investigate how to dilute a solution

Equipment:
Test tube rack
Test Tube
10ml measuring cylinder

Method:

Fill the measuring cylinder with 10 ml of water




put the water into the test tube



Add 5ml of water to the last 5 of the test tubes



Get a small spatula full of  Potassium manganite

Put the Potassium manganite into the 10ml of water and mix it

take 5 ml out of the first test tube

put five ml into the second test tube and mix

take 5ml out of the second test tube and put it into the third on and mix

take 5ml out of the third one and put it into the fourth one and mix it

take 5ml out of the fourth one and put it into the fifth one and mix

take 5ml out of the fifth one and put it into the sixth one and mix

Results:


The more time you take out the water and add it to water the mixture should be getting litter every time you add it to more water.

The reason why it is getting litter every time is because there is a different amount of water and Potassium manganite because you are taking it out of where there is more of the Potassium manganite
because it has less and less of the Potassium manganite and there is more water every time.
