Residue on ignition means the sample is ignited at higher
temperature in the muffle furnace for the period of time.
If it is not converted as a complete ash(grey colour)add
dilute sulphuric acid to the residue and evaporate the
acidic solution again keep into the furnace to convert ash
is called sulphated ash.
