a.
Interpretation: To give the name for the following description.
Concept Introduction: When two substances of the same type are mixed, they form a true solution. The particle’s size in a suspension is much larger than the solution that the particles settle down in the bottom. A colloidal solution is a heterogenous solution.
a.
Answer to Problem 78A
The descriptions that describe true solutions are 1,3,6 and 8.
Explanation of Solution
The given descriptions that represent a true solution are discussed as follows:
(1) The particles do not settle on standing.
(3) The size of the particle is less than 1 nanometer.
(6) One cannot see the particles with an unaided eye.
(8) An example of a true solution is salt water.

(7) Homogenized milk is an example of a colloidal solution.
(9) Jelly is another example of a colloid.
c.
Interpretation: To give the name for the following description.
Concept Introduction: When two substances of the same type are mixed together, they form a true solution. The particle’s size in a suspension is much larger than the solution that the particles settle down in the bottom. A colloidal solution is a heterogenous solution.
c.
