Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the year of publication?1833
2. What is the discoverer?Michael Faraday
3. What is Faraday's first law of electrolysis?Faraday's first law says the mass of a substance that comes out of or goes onto an electrode is directly proportional to the amount of electricity that passes through the liquid.
4. How does Faraday's second law help us compare different metals?Faraday's second law says that if the same amount of electricity is used, the masses of different substances that come out are proportional to their equivalent weights.

Electrolyte: A substance that conducts electricity when dissolved in water or melted, due to the presence of mobile ions.
Electrode: A conductor through which electricity enters or leaves an object, substance, or region, especially in electrolysis.
Equivalent Weight: The mass of a substance that will combine with or displace a fixed amount of another substance in a chemical reaction.
Redox Reaction: A chemical reaction involving the transfer of electrons between chemical species, involving oxidation and reduction.
