DEHYDRATING PROPERTIES
concentrated H2SO4 displays a very strong affinity for water, which is clearly reflected by the large amounts of heat evolved when the acid is mixed with excess water.
concentrated H2SO4 is used as a drying agent for air and gases such as O2, CO2, and N2
as the acid displays acidic and oxidizing properties, it cannot. however, be used to dry alkaline bases such as NH3 or reducing agents such as H2S
H2SO4 can also be used to remove hydrogen and oxygen atoms from compounds that do not contain water in a molecular form.
-
OXIDISING PROPERTIES
concentrated H2SO4 may act as strong oxidant, especially when hot
hot concentrated H2SO4 oxidises a number of non metal sp. such as sulfur, carbon and phosphorus

ACIDIC PROPERTIES
in the presence of strong base, NaOH the conversion of HSO-4 ions to SO4 -2 is virtually completed
although first hydrolysis is almost 100% complete, only about 10% of HSO-4 ionise
