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) If 25.00 mL of a 0.1 mol/L standard solution is used for titration at 10°C, then the equivalent volume at 20°C would be ( ) mL. It is known that the correction value for 1000 mL at 10°C when converted to 20°C is 1.45. A 25.04 B 24.96 C 25.08 D 24.92. Correct answer: A. Reply with your answer in the comments; you will receive +2 wealth points for participating in the quiz. An additional +3 to +8 wealth points will be given if you answer all questions correctly. Extra wealth points will also be awarded if you provide a thorough analysis and explanation of the questions or answers, including 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.
