NaOH solution + 酸 HCl -----> 鹽NaCl + 水H2O 此reation 是中和---neutralization . 不會出氯氣的 .
哥士的混合氯是會出漂白水 , 但是經electroylysis sodium chloride solution . In this chlorine & NaOH are formed at the opposite poles . If no dividing membrane is present & cooled contents are well mixed , sodium hypochlorite is formed : Cl2 + 2NaOH ---. NaOCl + NaCl + H2O . 但如果dilute NaOH + dilute NaOCl應該不會有reaction的 . 因為even concentrated 漂白水NaOCl 都是alkaline的 , 內含有哥士的 ! 但powder NaOH + concentrated NaOCl , 就有些chlorine走出來 , 因crystaline NaOH when is dissolved in water will evolve lots of heat which breaks down NaOCl to liberate some chlorine . But if add acid to NaOCl , an explosive reaction will be taken place .
Cleaner manufacture will not regard NaOCl is a cleaner , it is only a cheap , effective disinfectant & must be handled with great care !!!
