Answer: Strong electrolytes —Ammonium chloride, dilute hydrochloric acid, dilute sulphuric acid. A: Some lasers are allowed to claim 'permanent hair reduction'--that's not the same as Permanent Hair removal! Other examples of real life electrolysis are the production of sodium hydroxide and chlorine by the electrolysis of brine, and the refining of the metal copper. Which one of the following reactions is occurring at this electrode? A brown solid is seen to form around the zinc. What is the equation used to determine the mass percent of a solute in a solution? By the Movement of ions. In a molten solution, where water is not present, the metal atoms are always produced - this is how reactive metals like sodium and potassium are extracted from their ores.
