H_2—C1_2混合气在强光照射下发生爆炸的实验,可以证明C1_2的化学活泼性以及光对化学反应速度的影响,在化学教学上很有价值。只要采取适当的措施,实验是一定能够成功的,并且毫无危险。现将影响实验成效的因素以及应采取的措施,讨论于后: (一)混合气体的纯度问题
Experiments on the explosion of H_2-C1_2 gas mixture under strong light irradiation can prove that the chemical activity of C1_2 and the influence of light on the chemical reaction rate are very valuable in chemistry teaching. As long as appropriate measures are taken, the experiment will surely be successful and without any danger. Now factors that will affect the effectiveness of the experiment as well as the measures to be taken to discuss later: (a) the purity of the mixed gas
