Outline

4. How many ingredients does it need?
What happens to the mixture you've stirred? Did the
particles settle out? Is the color uniform throughout?
(Berapa banyak bahan yang dibutuhkan? Apa yang
terjadi pada campuran yang telah Anda aduk?
Apakah partikel-partikelnya mengendap? Apakah
warnanya seragam?)
Think of one mixture you've made at home, like
your favorite drink.
Think About It!

5. Define mixture (Pengertian campuran)
Differentiate between homogeneous and
heterogeneous mixtures. (Perbedaan antara
campuran homogen dan heterogen)
Compare and classify contrast solutions,
colloids, and suspensions (Bandingkan
dan bedakan larutan, koloid, dan suspensi)

SOLUTION
homogeneous
particle size: 0.01-1 nm (nanometer)
cannot be separated by filtration

12. milk gelatin mayonnaise
COLLOID
heterogeneous
particle size: 1 to 1000 nm
particles do not separate on standing
cannot be separated by filtration

dressing
muddy
water
SUSPENSION
heterogeneous
particle size: over 1000 nm
particles are large enough to settle
can be separated by filtration

14. two or more substances combined, yet can still be
separated into the original parts
can be homogeneous or heterogeneous
Solution - particle size between 0.01 - 1 nm
Colloid - particle size between 1 to 1000 nm
Suspension - particle size greater than 1000 nm
