Solutions?

Question

I have a science project tomorrow and i was wondering if these were soltuions/suspentions.

-Milk
-Egg White
-Egg Yolk
-Windex
-Pam
-Dawn
-Sodas

***** Please its a huge help

and Seltzer

Answer 1

Milk- Solution
Egg white - suspention
egg Yolk-suspention
Windex-solution
Pam- I don't know...What is it?
Dawn- solution
Sodas- solution

Answer 2

Actually there exists a "state" between solutions and suspension known as colloids. The truth of the matter is that these are all dispersed systems, i.e. one material dispersed in another. On the basis of the size of the dispersed material, we then classify the dispersions into one of three groups:

a) molecular dispersions, i.e. the dispersed material exists as molecules dispersed in the continuous phase. An example is a solution. The dispersed particles are invisible under the light and electron microscope and pass through filters and semipermeable membranes

b) colloids, such as protein solutions, polymer solutions, where the particles can be seen with the electron microsope

c) coarse dispersions, such as creams, suspensions and emulsions. The particles are visible under an ordinary microscope and do not pass through semipermeable membranes. Furthermore, a suspension implies that the dispersed substance is a solid, while an emulsion implies an oil dispersed in water or vice versa.

Thus, technically milk is not a suspension. Milk is an emulsion...in fact, if you leave milk to stand the fat layer separates on top of the water layer. The aqueous then, is a colloidal dispersion, because it has proteins dissolved in it.

Egg white contains mainly proteins, and is a colloidal dispersion in an aqueous base.

Egg yolk contains proteins and fats as a colloidal dispersion in a fat base.

Answer 3

The first three are suspensions, the last five are solutions.
