To increase the popularity of the chemical analysis section, a \"One Question per Day\" campaign has been launched to foster an active atmosphere for technical exchanges while also providing rewards in the form of financial benefits to users. 【Daily Question】 (Single-choice question) When electric current passes through an electrolyte, what is the relationship between the amount of substance that undergoes electrode reactions and the amount of electricity that passes through? ( ) A. Inverse proportion B. Direct proportion C. No proportional relationship D. Little relationship. Correct answer: B. Reply with your answer in the comments; you will receive +2 wealth points for participating in the quiz. An additional +3 to +8 wealth points will be given if you answer all questions correctly. Extra wealth points will also be awarded if you provide a thorough analysis and explanation of the questions or answers, or if you include detailed calculation processes. If your answer is correct and your analysis is accurate, it will be marked as the best reply (or the best assistance). Feel free to answer the questions.
Moderator, I got it right hahahahahah
B. Directly proportional: Faraday’s law of electrolysis states that, during the electrolysis process, the amount of oxidized substances deposited at the cathode is directly proportional to the intensity of the current passing through it and the time for which electricity is applied. M=KQ=KIt, where M is the mass of the deposited metal ； K—proportionality constant (electrochemical equivalent) ； Q—Amount of electricity passed ； I—Current intensity ； t—Power-on time.
When an electric current passes through the electrolyte, the relationship between the amount of substance that undergoes electrode reactions and the amount of electricity that passes is (B). A. Inverse proportion B. Direct proportion C. No proportional relationship D. Little relation
