%X The concentration of active chlorine and pH were analyzed in samplesof sodium hypochlorite 1% derived from three different bottles. Samples were stored in three bottles: bottle ¡°Pet 1¡±, ¡°Pet 2¡± and ¡°Pet 3¡±. One sample of each bottle was removed in the instant of opening the bottles (Time 0: T0). The other three samples (one of each bottle) have been exposed to the light and temperature during three hours and after that analyzed (Time 1: T1). The analysis of the results allowed to conclude that in all samples there was a decrease in the active chlorine concentration (T0JT1). The pH decreased from 12.00 to 11.50 (T0JT1) only samples deriving from bottle ¡°Pet 1¡±. The active chlorine percentage didn¡¯t correspond to the described on the bottles label.
