Which law states that the mass of a substance deposited or liberated at an electrode during electrolysis is directly proportional to the quantity of electricity passing through the electrolyte?
Answer and explanation
Correct answer: B. Faraday's First Law of Electrolysis
- Step 1: Michael Faraday formulated the first law of electrolysis: , or , where is the electrochemical equivalent.
- Step 2: The mass is directly proportional to the total electrical charge transferred.
Answer
Faraday's First Law of Electrolysis.
Why not the others: 'Ohm's Law' describes voltage and current in resistors (); 'Henry's Law' relates gas solubility to partial pressure; 'Raoult's Law' governs vapor pressures of ideal solutions.
