`P_2O_5` and `SO_2` are acidic oxides.

Both In_2O_3 and Tl_2O_3 are acidic/basic oxides.

Mn_2O_3 is acidic/basic oxide.

In the brown ring complex [Fe(H_2O)_5(NO)]SO_4 , nitric oxide behaves as

The acidic, basic or amphoteric nature of Mn_2O_7, V_2O_5 and CrO are respectively

SO_2 has acidic character. Explain.

In acid rain, SO_2 sulphuric acid accounts for

In the equilibrium 2SO_(2)(g)+O_(2)(g)hArr2SO_(3)(g) , the partial pressure of SO_(2),O_(2) and SO_(3) are 0.662,0.10 and 0.331 atm respectively . What should be the partial pressure of Oxygen so that the equilibrium concentrations of SO_(3) are equal ?

Write chemical equation for : Oxidation of SO_3^(2-) by Cr_2O_7^(2-) in acidic medium.

Write chemical equation for :Oxidation of Fe^(2+) by Cr_2O_7^(2-) in acidic medium .
