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 chemical burns caused by acids, it is necessary to rinse with plenty of water, then rinse with ( ), and afterward rinse again with water. A 0.3mol/L HAc solution B 2% NaHCO3 solution C 0.3mol/L HCl solution D 2% NaOH solution. Correct answer: B. Reply with your answer in the comments; participating in the quiz earns you +2 wealth points. Those who get all answers correct will receive an additional +3 to +8 wealth points. Those who provide a thorough analysis and explanation of 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 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.
