Flame Tests Of Metals


Bought sparklers , among other things for diwali . Its looked at as childs play , and one feels silly holding this sparkling rod and moving it in patterns like a stupid kid ......

A sparkler burns slowly for a long time while a cracker is more like a controlled explosion . Very simply put , a sparkler is made by .......

Once it is lit , the metal flames heat up be come incandescent ( give off light ) and start to burn emitting various colours ....and i guess the bluish green sparklers that i love so much have their colour only because of copper flakes .

Now i sure wish that i had paid a little more attention in the Chemistry lab at school . Any ways this brings me to the question of flame tests of metal - the colour shart is in the picture- which i had done in 9th Standard and cooly forgotten till now .
