Abstract
An experimental method to calculate average metal ions charge by electrolysis at different temperatures is proposed. Direct electric current and anode mass decreasing were measured during electrolysis into concentrated NaCl solution at room temperature and 100oC. Averagecharges of copper, iron, and aluminium ions were calculated using Faraday’s law of electrolysis: +3 for aluminium; +2 for iron; and +1 for copper at room temperature, and +3 for aluminium; +2 for iron; and +1.5 for copper at temperature 100oC.
