Assignment Help:

Borax bead test : The transparent glassy bead while heated along with inorganic salt and the colour produced gives some idea of cation present in it.

Table:

Colour of bead in oxidising flame	Colour of bead in reducing flame	Basic radical present
Greenish when hot, blue in cold.	Red and opaque	Cu
Dark green in hot and cold	Same	Cr
Deep - blue	Deep blue	Co
Yellow when hot	Green	Fe
Violet in hot and cold	Colourless	Mn
Brown in cold	Grey or black or opaque	Ni
