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 purpose of adding pyridine in the oxime method for determining carbonyl compounds is ( ). A. Catalyst B. Adjusting the acidity of the solution C. Inhibiting the reverse reaction D. Accelerating the reaction rate. Correct answer: C. Post your answer in the replies; participating in the quiz earns you +2 wealth points. Getting all answers correct grants 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/explanation is accurate, it will be marked as the best reply (or the best assistance). Feel free to answer the questions.
The purpose of adding pyridine in the oxime method for determining carbonyl compounds is (C) to inhibit the reverse reaction from occurring
The answer to this question should be B. In the acid hydroxylamine-pyridoxime method for determining the content of carbonyl compounds, pyridine is added to combine with the resulting acid salt in order to reduce the acid concentration and suppress the reverse reaction.
The purpose of adding pyridine in the oxime method for determining carbonyl compounds is (C). A Catalyst B Adjust the acidity of the solution C Inhibit the occurrence of the reverse reaction D Accelerate the reaction rate
