PRAKTIKUM SOLUTION, COLLOID DAN SUSPENSION


 THE CLASSIFICATION OF COLLOID

I.                    AIM
Ø  To Know the difference between solution, colloid and suspension

II.                   BASIC THEORY
  A mixture of water and sugar is called a solution / suspension of molecular, meaning a mixture where the molecules of the solute (sugar), spread evenly in the solvent molecules (water). This mixture is called a homogeneous mixture. Example: alcohol, salt water, vinegar, syrup, etc..

              The mixture of water and milk called colloid, which is between homogeneous and heterogeneous mixture. Examples: fog, ink, smoke, etc.

            Between sand and water mixture called a suspension of crude, which is a mixture that consists of two parts, namely sediment and filtrate (heterogeneous mixture).

III.                TOOLS AND MATERIALS
a)      Tools
Ø  Chemistry glasses 9 seed
Ø  Flask glasses 3 seed
Ø  Spoon
Ø  Funnels  3 seed
Ø  Filter Papers 9 sheet
Ø  A bottle of aquades

b)      Materials
Ø  Sand
Ø  Salt
Ø  Coffee
Ø  Milk
Ø  Corn Flour
Ø  Shampoo
Ø  Powder
Ø  Sauce
Ø  Body Lotion
Ø  Rice Flour
IV.                STEPS
a.)    Prepare all tools and materials which we need on the practice table
b.)    Then, enter the sand to the chemistry glass
c.)     Next, ad the aquades to the chemistry glass ( solution )
d.)    And then, stir until each solution in the chemistry glass until is flat
e.)    Then, let stand until ± 5 minutes and observe
f.)     Next, stir again the solution
g.)    And then, filter the solution wit funnel and filter paper on the top
h.)    Then doing the activity of  B until G for solution Salt, Coffee, Milk, Corn Flour, Shampoo, Powder, Sauce, Body Lotion, Rice Flour
i.)      Finally, write Down the result of observation !
j.)

VI.                CONCLUSION

The conclusion of the experiment of The Colloid Classification, we can know that the difference between solution, colloid, and suspension can be observed the following table
