Chapter 9: Q. 9.63 (page 313)

Identify each of the following as characteristic of a solution, colloid, or suspension:

a. a mixture that cannot be separated by a semipermeable membrane

b. a mixture that settles out upon standing

Short Answer

Expert verified

(part a) A mixture that cannot be separated by a semipermeable membrane having the characteristics of solution.

(part b) A mixture that settles out upon standing, having the characteristics of suspension.

Step by step solution

01

Introduction (part a).

Filters can differentiate atoms in a suspension. Droplets suspended in a suspended settle out. Colloids consist of materials that are in between those found in a solution as well as those found in a suspension.

02

Given Information (part a).

Given:

A mixture that cannot be separated by a semipermeable membrane

03

Explanation (part a).

The characteristic property of solution is that it is a mixture that cannot be separated by a semipermeable membrane.

04

Given Information (part a). 

Given:

A mixture that settles out upon standing.

05

Explanation (part b).

Suspension is characterized by a mixture that settles out after standing.
