Question
Chapter 4, Problem 4.91E
Interpretation Introduction
Interpretation:
The way in which the sizes of a metal atom and a positively charged ion of the same metal would compare is to be stated.
Concept introduction:
Every element attains an electronic configuration same as that of a noble gas. To do so, elements either gain or lose electrons. When an atom of an element gains electrons, it forms an anion. When an atom of an element loses electrons, it forms a cation.

- 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?
