Residue on ignition means at a define temp.
(about 600 deg C). how much matter driven off form your
sample means after ending the test you will get the residue
on ignetion all part of organic matter will removed and
only inorganic matter will present because we are finding
how much inorganic impurity present in sample.

Answer / swapna
Residue on ignition is useful to identification of inorganic substances present in the sample.while adding the sulfuric acid metals reacts with sulfuric acid to form their sulphates

Answer / sandeep kale (toronto, canada)
ROI / Sulfated Ash Test is use to find out Inorganic Impurities.
At 600-800°c all the metal salts (Used as a catalyst in formation of Intermediates / API'S)(which are soluble) gets converted in to metal oxides (Insoluble and Highly Non volatile).
And final residue we get , of Metal Oxides which are Inorganic Impurities.
