solutions

Question 1

solutions

Answer 1

homogeneous mixtures of two or more substances in a single phase

sugar-water solution

Question 2

soluble

Answer 2

capable of being dissolved in a particular solvent

Question 3

solvent

Answer 3

in a solution, the substance in which the solute is dissolved

Question 4

solute

Answer 4

the substance dissolved in a solution.
the substance that is present in smallest quantity.
can be gas, liquid, or solid.

Question 5

suspensions

Answer 5

if the particles in a solvent are so large that they settle out unless the mixture is constantly stirred or agitated (sand and flour in water)

Question 6

colloids

Answer 6

particles that are intermediate in size between those in solutions and suspensions from mixtures known as colloidal dispersions (fog, jelly, butter) (mostly cloudy)

Question 7

electrolyte

Answer 7

a substance that dissolves in water to give a solution that conducts electric current.
any soluble ionic compound is an electrolyte.
strong acids are electrolytes.
(Sodium, Potassium, Magnesium)

Question 8

nonelectolyte

Answer 8

a substance that dissolved in water to give a solution that does non conduct an electric current
Sugar

Question 9

Heterogeneous mixture

Answer 9

composition is not uniform
milk, soil (composed of other stuff)

Question 10

Homogeneous mixture

Answer 10

ions and water molecules are in a random arrangement and is uniform
salt, water molecules

Question 11

miscible liquids

Answer 11

easily dissolve in one another (carbonated water and orange juice)

Question 12

immiscible liquids

Answer 12

not soluble in each other (water and oil)

Question 13

saturated

Answer 13

solutions containing undissolved solute in equilibrium with the solution (soda)

Question 14

unsaturated

Answer 14

solution containing less than the maximum amount of solute (vinegar)

Question 15

supersaturated

Answer 15

solution containing more solute than is normally allowed (sodium acetate)

Question 16

solvated

Answer 16

a solute particle that is surrounded by solvent molecules

Question 17

concentration

Answer 17

measure of the amount of a substance (solute) in a mixture or a solution

Question 18

molality

Answer 18

the concentration of solution expressed in moles of solute per kilogram of solvent
moles solute/Kg solvent

Question 19

molarity

Answer 19

the number of moles of solute on one liter of solution
moles solute/L solution

Question 20

Tyndall effect

Answer 20

when light is shined through a solution, the light passes clearly through the solution. when light is passed through a colloidal solution, the substance in the dispersed phase scatters the light in all directions.

Question 21

Factors affecting the rate of dissolution:

Answer 21

increase of surface area of solute
stirring or shaking (agitating the solution),
increase temperature (heating the solvent)

Question 22

solute equilibrium

Answer 22

the physical state in which the opposing processes of dissolution and crystallization of a solute occur at equal rates.
