宏观与微观相联系是化学学科独特的思维方式,从宏观现象可以透视微观实质,利用微观理论可以解释宏观变化。大家对于图1这个实验一定不陌生吧?这是探究分子运动现象的实验。实验中,从A烧杯的浓氨水中挥发出来的氨分子不断运动,进入B烧杯,溶解在酚酞溶液中,使无色酚酞溶液逐渐变成红色。该实验说明,分子总是在不断地运 Macroscopical and microcosmic connection is a unique way of thinking in chemistry. From the perspective of macroscopic phenomena, we can see the essence of microcosm and use macroscopic theory to explain macroscopic changes. We are not unfamiliar with this experiment in Figure 1. This is an experiment to explore the phenomena of molecular movement. In the experiment, the ammonia molecules volatilized from the concentrated ammonia water of A beaker continuously moved into B beaker and dissolved in the phenolphthalein solution to make the colorless phenolphthalein solution gradually turn red. The experiment shows that molecules are always transported
