dissolved into another.
● Uniform all throughout
which makes it homogenous

Answer 19

Solution

Question 20

● degree to which a substance dissolves
in a solvent to make a solution (usually

Question 23

*The substance that does the dissolving
● Any substance, generally liquid, which
is capable of dissolving one or multiple
substances, which produces a solution.

Answer 23

Solvent

Question 24

● Substance that is dissolved in a solution
● The particles of solute in a solution cannot be
seen by the naked eye.
● A solution does not allow beams of light to
scatter.

Answer 24

solvent

Question 25

also known as the Tyndall phenomenon, ● is the scattering of a light beam by a medium containing microscopic suspended particles

Answer 25

tyndall effect

Question 26

Answer 27

Unsaturated solution

Question 28

can be defined as a solution in which a solvent is not capable of dissolving any more solute at a given temperature.

Answer 28

Saturated solution
