在许多中级无机化学实验教材中常选用电合成K_2S_2O_8的内容。K_2S_2O_8是一种高价态的含氧酸盐,它具有很强的氧化性,难以用一般的化学方法制备。通常采用无隔膜电解KHSO_4饱和水溶液的方法合成。一般的电解条件是在低温下电解饱和KHSO_4水溶液並采用铂丝
In many intermediate inorganic chemistry experimental materials often choose the synthesis of K_2S_2O_8 content. K 2 S 2 O 8 is a high valence oxygenate that has strong oxidizing properties and is difficult to prepare by conventional chemical methods. Usually without diaphragm electrolytic KHSO_4 saturated aqueous solution synthesis. The general electrolysis conditions are electrolysis of KHSO_4 aqueous solution at low temperature and the use of platinum wire
