查询词典 cobalt

Process:① the platinum wire dipped in concentrated hydrochloric acid to colorless colorless flame on the ignition;②sample in the colorless flame ignition, to observe the flame color (if test potassium cobalt glass through observation, because in most cases need to be used when the system of potassium sodium, potassium solution, therefore often contain sodium, and sodium yellow flame color reaction, a small amount of yellow and purple, respectively, can not come out).

3操作过程：①将铂丝蘸浓盐酸在无色火焰上灼烧至无色；②蘸取试样在无色火焰上灼烧，观察火焰颜色(若检验钾要透过钴玻璃观察，因为大多数情况下制钾时需要用到钠，因此钾离子溶液中常含有钠离子，而钠的焰色反应为黄色，黄色与少量的紫色无法分别出来)。
