To increase the popularity of the chemical analysis section, a \"One Question per Day\" campaign has been launched; this aims to foster active technical exchanges while also providing financial rewards to users. 【Daily Question】 (Single-choice question) In potentiometric titration, when using a potassium permanganate standard solution to titrate Fe2+, which electrode is suitable as an indicator electrode? A pH glass electrode B silver electrode C platinum electrode D fluoride electrode. Correct answer: C. Reply with your answer in the comments; participating in the quiz earns you +2 wealth points. Those who get all answers correct receive an additional +3 to +8 wealth points. Those who provide thorough analyses and explanations for the questions or answers, or include detailed calculation processes, will receive extra wealth points as a reward. 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. Note: We will close this post after 24 hours, and at that time we will announce the best reply (the best assistance), as well as the answer and explanation.
