The Electrolysis Calculator calculates the mass of a substance deposited or the required current/time during electrolysis using Faraday’s laws. Based on the formula m=ItMnFm = \frac{I t M}{n F}m=nFItM​, it relates electric charge to the amount of substance produced at an electrode. By entering known values such as current, time, molar mass, and number of electrons, the calculator determines the missing variable. This tool is ideal for chemistry and electrochemistry students to understand the quantitative relationship between electric current and chemical change in electrolytic cells.
