Thermal Decomposition and Precipitation
Breaking down with heat
Transition metals break down and cause a colour change
Copper(II) carbonate
Iron carbonate
Zinc carbonate
Manganese carbonate
Break down into a metal oxide and carbon dioxide
Precipitation
2 solutions react and you get an insoluble solid in the solution
some soluble transition metals compounds react with sodium hydroxyde
Copper sulphate + sodium hydroxide = copper hydroxide + sodium sulphate
Iron sulphate + sodium hydroxide = iron hydroxide + sodium sulphate
Transition metal ions
Insoluble transition metal hydroxides have distinctive colours
