Why sulpuric acid only used to ROI but not used nitric acid
and some other acids?

Answer / ankur dwivedi
As we generally check the inorganics by this test by
converting it into their sulphates with the treatment of
H2SO4 and sulphates are very stable at high temperature
(about up to 800-1000). while nitrates and chlorides are
not stable at high temperature. Hence it is recommended to
go for sulphated ash instead of nitrates and chlorides.

H2so4 . Will
convert the all
inorganic
nonvolatiles in to
their sulphates .
Sulphates are more
stable at the
specified
temporature in ROI
test the other
acids .

Answer / amarendra allu
sulpuric acid is strong acid and after addition of H2SO4 ORGANIC COMPOUND WILL DECOMPOSED AND VAPORISED BY IGNITING. ROI IS CONTENT OF INORGANIC ,after addition of H2SO4 to compound it converting into their sulphates with the treatment of H2SO4 and sulphates are very stable at high temperature
(about up to 800-1000). while nitrates and chlorides are
not stable at high temperature.

Answer / satish kumar
Basically H2SO4 is strong acid than other acids so it can react with any inorganic impurities into organic compound then it converts into their sulphates salt ..... sulphates are more stable at high temperature while compare with any other acids like nitric acid also....
Sulphates are easily reacts with inorganic compounds to be form as salts due to its strong oxidising nature and more stable but incase of nitrates its occurs in slowly and not stable at high temperature up to 600...

To check inorganic impurities in form sulphated ash to add
h2so4 stable at high temp than other inorganic acid.

Answer / ikhlakh
Because we report ROI in the form of sulphate salt so we
add sulphuric acid insteed of nitric acid.
