Question
Chapter 20, Problem 56A
Interpretation Introduction
Interpretation:
The term
Concept introduction:
Poly means many and mer means unit. Thus, polymer is repetition of units.
Expert Solution & Answer
Answer to Problem 56A
A polymer is a material which is made of a large number of subunits. Each subunit is called monomer.
Explanation of Solution
Polythene is an example of polymer. It is polymer of ethene. A number of units of ethene join together and forms polythene. Thus, ethene is monomer and polythene is polymer.
Polymers are of three categories:
- Natural
polymers - Synthetic polymers
Semi-synthetic polymers
Natural polymers are the polymers which are obtained in nature. Example: starch
Synthetic polymers are the polymers which are man-made. Example: Teflon
Semi-synthetic polymers are the polymers whose sources are natural and some modifications are done to improve the properties. Example: Vulcanised rubber
Conclusion
Thus, monomer combines in a large number to form polymers.

- You wish to add enough NaOCl (sodium hypochlorite) to a 150 m³ swimming pool to provide a dose of 5.0 mg/L TOTOCI as Cl2. (a) How much NaOCI (kg) should you add? (Note: the equivalent weight of NaOCl is based on the reaction: NaOCl + 2H + 2 e→CI + Na +H₂O.) (10 pts) (atomic weight: Na 23, O 16, C1 35.5) (b) The pH in the pool after the NaOCl addition is 8.67. To improve disinfection, you want at least 90% of the TOTOCI to be in the form of HOCI (pKa 7.53). Assuming that HOCI/OCI is the only weak acid/base group in solution, what volume (L) of 10 N HCl must be added to achieve the goal?
