To increase the popularity of the chemical analysis section, the previous 【Weekly Topic】 activity has been replaced with a 【Daily Question】 activity, which not only fosters an active atmosphere for technical exchanges but also provides rewards in the form of financial incentives to users. 【Daily Question】 (Single-choice question) When using chemical absorption to determine the CO2 content in industrial gases, which absorbent should be chosen? ( ) A. NaOH solution B. KOH solution C. Ba(OH)2 solution) Please reply with your answer; participating in the quiz earns +2 wealth points. Those who get all answers correct will receive an additional +3 to +8 wealth points. Extra rewards will be given for thorough analyses and explanations of the questions or answers, or for 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. 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.
