WebTake an example of electrolysis of copper (II) sulphate solution using platinum electrodes. By ionic theory, the solution ionizes thus: CuSO 4 (aq) → Cu 2+ (aq) + SO 4 2-(aq) (strong electrolyte) H 2 O⇔ H + + OH – (weak electrolyte) During electrolysis, Cu 2+ and H + ions move to the cathode while SO 4 2-and OH – ions move to the anode. WebApr 14, 2024 · Electrolysis is considered a more permanent hair removal solution than laser hair removal. With electrolysis, each hair follicle is treated individually, making it more effective in preventing future hair growth. Laser hair removal can only temporarily reduce hair growth, and maintenance sessions may be required to maintain the results. Webchromium(III) as chromic ion.
