如何獲取游離基(作實驗用)20點

By simple chemical reaction of dilute HNO3 with metal Cu, NO radical can be produced. Very good ventilation is required for this experiment. Please note!!

3Cu + 2HNO3 + 6H+ --> 3Cu2+ + 4H2O + 2NO

NO (nitrogen monoxide or nitrogen(II) oxide) is an example of free radical.

記憶中， 三苯甲基自由基 是一個穩定性高的自由基，可用瓶子存起來，橙色 / 黄色？咁上下啦！


能夠在哪買到?
如不能買,如何製造?

對不起，答你唔到。

Yes, Nitrogen monoxide has odd electron on nitrogen atom. It is a free radical.
