Chapter 1, Problem 28A

Interpretation Introduction

Interpretation:

Common uses of chlorofluorocarbons needs to be explained.

Concept introduction:

Chlorofluorocarbon was first synthesized in 1928 by Thomas Midgley, Jr. It is composed of three elements of the periodic table, chlorine, fluorine and carbons.

Answer to Problem 28A

Chlorofluorocarbons are used as solvents, blowing agents, manufacturing agents in aerosol sprays and refrigerants.

Explanation of Solution

Chlorofluorocarbon is composed of three elements of the periodic table, chlorine, fluorine and carbons. There are several substances that are classified as chlorofluorocarbons or CFCs.

It does not occur naturally, it can only be obtained in laboratory. It is a non-toxic and stable gas because it does not react with other substances.

Chlorofluorocarbons are used as:

• As coolants in refrigerators and air-conditioners.
• As blowing agents in plastic foams and packing materials.
• In spray cans as propellants.
• And as solvents.

Conclusion

Hence, some common uses of chlorofluorocarbon is its usage as manufacturer of aerosol sprays, as blowing agents in plastic foams and packing materials and as refrigerant.
