If you weren't a chemist, you'd know sodium hypochlorite (NaClO) as bleach, or possibly as the "chlorine" you put in your swimming pool or spa. NaClO solution is a convenient way to handle chlorine in an aqueous solution; it is prepared by absorbing chlorine gas in sodium hydroxide solution. Industrially, NaClO solution is produced directly by electrolyzing sodium chloride solution.

Sodium hypochlorite (NaClO)聽has been widely used for >200 years; but until now, the crystal structure of its pentahydrate (the normal solid form) had not been established. Tomislav Fri拧膷i膰 and co-workers at McGill University (Montreal), working at 鈥�100 掳C because NaClO鈥�5H2O liquefies at ambient temperature, determined the , shown. The structure consists of alternating layers of Na+ and ClO鈥� ions 鈥済lued鈥� together by water molecules.
