在今年高考化学试题中有这样一题,给出甲、乙、丙、三个装置,并说明是分别用来进行溶解度的测定、苯的硝化和苯酚跟甲醛的缩聚三个实验的,要求填空回答甲、乙、丙各适用于进行何项实验。本来,只要考生熟悉实验装置图,是不难得全分的,然而,仍有不少学生在这道简单、直观的题目上丢了分,这是很可惜的。 In this year’s college entrance examination chemistry test question, there are such a question, given A, B, C, and three devices, and instructions are used to perform the solubility measurement, benzene nitration, and polycondensation of phenol with formaldehyde three experiments, required to fill in the blank Answers A, B, and C apply to what experiments are performed. Originally, as long as the candidate is familiar with the experimental device map, it is not difficult to get full marks. However, there are still many students who lose points on this simple and intuitive topic. This is a pity.
