ok i had to heat hydrated cobalt chlorine

we used a bunsen burner

it was red before heating and after it turned white

what happened to cause this?

I was thinking that some of the chlorine got burnt off and it reverted to the dominant color group cobalt

or that it was supersaturated but the results dont show this. there was a loss of mass..

so anyone know ?

Sure it does. It was not so much white but a bluish-white.

Could be color change is misleading. You start with the red one, it gets blue on heating, and then gets whiter and whiter... But it should never loose the weak blue tint.
