Samuel Science Flashcards

Mixtures can be made from:

2 or more physically combined substances whose properties remain unchanged

Diffusion

dispersion of substances in a gas or liquid

Solution

type of homogeneous mix, one substance is dissolved into another

Heterogeneous Mixture

combination of substances not well mixed and still visible

Separating solutions vs supensions

solution particles are dissolved while the suspension particles can be filtered out

Relationship between solute and solvent

form a solution

solute

gets dissolved

solvent

does the dissolving, the base of the solution

3 ways to separate homogeneous mixtures

decanting, filtration, sifting

Ways to separate mixtures

decanting, filtration, sifting

Main types of mixtures (2)

homogeneous, heterogeneous

Homogeneous Mixture

substances are evenly mixed and distributed

sifting

separating different sized particles with a filter

filtration

separating a solid from a liquid using a filter

decanting

carefully pouring a liquid to separate it from sediments or another liquid

mixture

combination of two or more substances, can still be separated

pure substance

material made of only one type of substance

example of pure substance

any element (like gold)

example of mixture

trail mix

example of solution

sugar water

Colloid

heterogeneous mixture where fine particles are suspended in a solid, liquid, or gas, and don’t settle

suspension

heterogeneous mixture where bigger particles are suspended in a solid, liquid, or gas, but can settle
