Assertion (A) Ferricyanide ion oxidises H _(2) O _(2) to H _(2)O in basic medium. Reason ® Oxidation product of H _(2) O _(2) is O _(2), Which of the following is true ?

K_2SO_4 . Al_2 (SO_4)_3. 24 H_2O is

H_2O_2 + H_2O to H_2O^(+) toHO_2^- This reaction indicates

2H_(2) O_(2) to 2 H_(2)O_ + O_(2) . This reaction is

Passage - VI : Industrially sulphuric acid is produced by the following steps: Stage I : S+O_(2) overset(Delta)to SO_(2) Stage II : 2SO_(2) +O_(2) overset(V_(2)O_(5))to 2SO_(3) Stage III : SO_(3)+H_(2)O to H_(2)SO_(4) Since the reaction between SO_(3) and H_(2)O is violent, SO_(3) is passed into 98% H_(2)SO_(4) to produce oleum (H_(2)S_(2)O_(7)) Pure H_(2)SO_(4) does not react with metal because -

Match the following 1) Plaster of Paris 1) CaSO_412H_2O b) Gypsum 2) Na_2CO_3*10H_2O c) Washing soda CaSO_4*2H_2O

Passage - VI : Industrially sulphuric acid is produced by the following steps: Stage I : S+O_(2) overset(Delta)to SO_(2) Stage II : 2SO_(2) +O_(2) overset(V_(2)O_(5))to 2SO_(3) Stage III : SO_(3)+H_(2)O to H_(2)SO_(4) Since the reaction between SO_(3) and H_(2)O is violent, SO_(3) is passed into 98% H_(2)SO_(4) to produce oleum (H_(2)S_(2)O_(7)) Ionically the reaction between H_(2)SO_(4) & Mg may be presented as, Mg+2H_(3)O^(+) to Mg^(2+)+H_(2) uarr +2H_(2)O Therefore, in the given reaction -

Consider the following reactins involving some atmospheric pollutants. NO + O_(3) to NO_(2) + O_(2) overset(hv) to NO + O_(3) 4NO _(2) + O _(2) + 2H_(2)O to 4HNO_(3) 3CH_(4) + 2O_(3) to 3H_(2) C=O+ 3H_(2)O Based on the above, the formation of formaldehyde from methane in the atmosphere will be controlled by,

(i) H_(2)O_(2)+O_(3)toH_(2)O+2O_(2) (ii) H_(2)O_(2)+Ag_(2)O to 2Ag+H_(2)O+O_(2) Role of hydrogen peroxide in the above reaction is respectively
