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) The height of the funnel during the filtration process is determined by the outlet of the funnel neck ( ). A 5 mm below the edge of the beaker; B in contact with the bottom of the beaker; C not in contact with the filtrate; D at the center of the beaker. Correct answer: C. Reply with your answer in the comments to participate – you will receive +2 wealth points. If you answer all questions correctly, you’ll get an additional +3 to +8 wealth points. Those who provide thorough analyses and explanations for the questions (or include detailed calculation processes) will receive extra wealth points as well. 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. 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.
