Unit 8.1-8.5

Question 1

saturated solution

Answer 1

maximum amount of dissolved solute

Question 2

solubility

Answer 2

measure of the maximum amount of solute that will dissolve in a given amount of solvent at a given temperature

Question 3

unsaturated solution

Answer 3

less than maximum solute is dissolved (more could be dissolved)

Question 4

supersaturated solution

Answer 4

more than maximum solute (crystals usually appear)

Question 5

colloid

Answer 5

medium solute, doesn’t settle, light scatters - fog, milk, mayo

Question 6

solution

Answer 6

small solute, doesn’t settle, light passes through - kool aid, jello, sugar water, salt water

Question 7

solute

Answer 7

the dissolved substance; part of the solution that’s of lesser quantity

Question 8

solvent

Answer 8

does the dissolving; larger quantity of solution

Question 9

suspension

Answer 9

large solute, settles over time, light doesn’t pass through - muddy water, orange juice w pulp, sandy water

Question 10

soluble

Answer 10

capable of being dissolved

Question 11

why do chemical compounds tend to dissolve more quickly in hot solvents than in cold solvents?

Answer 11

rising temps. spread molecules out so they dissolve quicker

Question 12

equation used to dillute solutions

Answer 12

C1V1 = C2V2 or M1V2 = M2V2
