Identifying the products of electrolysis - RSC Education
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. Note that in many of the stated problems, acid is not shown and the products water, H+1 and OH-1 are left out initially. Sn+2(aq) + Cr 2O7-2(aq) → Sn+4(aq) + Cr+3(aq) Write the oxidation and the reduction equations separately, with the oxidation numbers written above each species. soft tissue bone cancer
