concentrated sulphuric acid

concentrated sulphuric acid is both dehydrating and oxidizing.illustrate this statement with the action of concentrated sulphuric acid on glucose(C6H12O6).write balanced equationsfor the reactions involved.

我淨係知道dehydrating 果條係C6H12O6--------------------------)6C(s)+6H2O

oxidizing果條係點0.0 .. 謝謝

It will further oxidize C(s) formed into CO2(g)
C(s) + 2 H2SO4(l) --> CO2(g) + 2 SO2(g) + 2 H2O(l)
Since oxidation number of C increases from 0 (C) to +4 (C in CO2),
concentrated sulphuric acid thus is an oxidizing agent
