咩係次氯鈉酸

次氯酸鈉 (Sodium hypochlorite)

漂白水是一種而有效的家居消毒劑，其主要成分是次氯酸鈉 (Sodium hypochlorite)，能使微生物的蛋白質變質，有效殺滅細菌、真菌及病毒。家用漂白水到處有售，且價錢廉宜，功效快速，因此，市民可使用稀釋的家用漂白水來消毒環境。

成日淨post英文比人ｘ，今次整個中英對照版先XD

Sodium hypochlorite has the ability for bleaching. Thus acting as a good disinfectant.

次氯鈉酸(Sodium hypochlorite)有漂白能力，因此通常用於各種消毒用途

Sodium hypochlorite may be prepared by absorbing chlorine gas in cold sodium hydroxide solution:

次氯鈉酸可由冷凍的氫氧化鈉和氯氣產生化學反應而成

其化學反應方程式是：

2NaOH + Cl2 → NaCl + NaClO + H2O

Mechanism of sterilization power：

Hypochlorite ion can easily diffuse through the cell walls of bacteria and virus. This changes the oxidation-reduction potential (ORP) of the cell, and inactivates the enzyme triosephosphate dehydrogenase. Triosephosphate dehydrogenase (or glyceraldehyde 3-phosphate dehydrogenase/GAPDH) is essential for the digestion of glucose, but is particularly sensitive to oxidizing agents. Its inactivation effectively destroys the micro-organism's ability to function.

消毒作用機製：

次氯酸斤離子(唔知係咪咁translate)是一種氧化劑，它可輕易穿透細菌和病毒的細胞壁，將細胞的氧化還原勢改變，透過氧化作用將triosephosphate dehydrogenase變得不活躍。這樣便能令細菌和病毒喪失致病的能力。

Translate得好辛苦，比下面XD

NaCl is a salt
