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 hydroxyl value refers to ( ). The amount of hydroxyl groups in 100g of sample is equivalent to the number of grams of potassium hydroxide. B: The amount of hydroxyl groups in 1g of sample is equivalent to the number of grams of potassium hydroxide. C: The amount of hydroxyl groups in 100g of sample is equivalent to the number of milligrams of potassium hydroxide. D: The amount of hydroxyl groups in 1g of sample is equivalent to the number of milligrams of potassium hydroxide. Correct answer: D. Please reply with your answer; participating in the quiz earns +2 points, and getting all answers correct adds another +3 to +8 points. Those who provide a thorough analysis or explanation of the questions and answers, or include detailed calculation processes, will receive additional points as a reward. If your answer is correct and your analysis is accurate, it will be marked as the best reply (or 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.
