电解法制备化学物质是大规模工业制备的主要方法之一,如电解食盐水溶液可得到重要化工产品烧碱、氯化和氢气,电解无水熔融的金属盐类(如氯化物)可得到相应的金属等。当产物难于分离时,电解也是常用的最好的合成方法。电解法通常用于制取较高或较低氧化态的化合物,K_2S_2O_8是已知 Electrolytic preparation of chemical substances is one of the major methods of large-scale industrial preparation, such as electrolysis of saline solution can be important chemical products caustic soda, chlorination and hydrogen, electrolysis of anhydrous molten metal salts (such as chloride) can be obtained corresponding metal Wait. When the product is difficult to separate, electrolysis is also the best commonly used synthesis method. Electrolysis is commonly used to make higher or lower oxidation state compounds, K 2 S 2 O 8 is known
