Capters 12&13- Solutions

Question 1

mixture

Answer 1

a combination of two or more substances that are not chemically combined

Question 2

heterogeneous

Answer 2

composition is not uniform

Question 3

homogenous

Answer 3

uniform composition

Question 4

solution

Answer 4

a homogenous mixture of two or more substances in a single phase

Question 5

two parts of a solution

Answer 5

solvent and solute

Question 6

solvent

Answer 6

dissolving medium

Question 7

solute

Answer 7

substance being dissolved

Question 8

solution

Answer 8

true solution: solute particles are too small to be seen
solute particles remain uniformly mixed with the solvent
solute particles are the size of atoms/ molecules

Question 9

colloid

Answer 9

solute particles are much larger than molecules/ atoms of the solvent
solute particles range from 1-1000 nm
solute particles are too large to be completely uniform in dispersion, but small enough to be suspended throughout the solvent
colloidal particles make up dispersed phase
solvent particles make up dispersing medium

Question 10

suspension

Answer 10

solute particles are so large that they settle out unless solution is constantly agitated

Question 11

tyndall effect

Answer 11

particles in a colloid will always be large enough to scatter light
