鲁科版化学必修1第三章第一节“活动·探究”要求对Na_2CO_3和NaHCO_3的化学性质通过设计实验进行比较,笔者现提出适合教师演示和学生实验的三种可行性设计方案,以供同行参考。一、利用传统仪器进行创新设计1.实验用品注射器2支(20 mL)、具支U形管1支、小气球2个、橡胶塞2个、铁架台1个、0.5 mol/L Na_2CO_3溶液、 Luke version of the required chemistry 1 chapter III of the first chapter “activity inquiry ” requirements on the chemical nature of Na_2CO_3 and NaHCO_3 by comparing design experiments, the author now presents three feasible design for teacher presentations and student experiments, For peer reference. First, the use of traditional instruments for innovative design 1. Experimental supplies Syringe 2 (20 mL), with a support U-shaped tube, a small balloon 2, 2 rubber stopper, a Taiwan iron frame, 0.5 mol / L Na_2CO_3 solution,
