Match the reactions in Column I with type of the products/applications

1.	Match the reactions in Column I with type of the products/applications in Column II. {:("Column I","Column II"),((A),(p)"Turnbull's blue pigment"),((B)BaCl_2(s)+K_2Cr_2O_7(s)+H_2SO_4("conc.")to,(q)"Schwitzer's reagent"),(( C)FeSO_4(aq)+K_3[Fe(CN)_6](aq)to,(r)"Reimann's green pigment"),((D)Cu(OH)_2(s)+NH_4OH(aq)+(NH_2)_2SO_4(s)to,(s)"Chromyl chloride test"),((E)ZnO(s)+Co(NO_3)_2(s)oversetDeltato,"(t)Photography"):}
Answer» Solution :(A) Hydroquinone acts as developer (B)`BaCl_2+K_2Cr_2O_7+3H_2SO_7+3H_2SO_4 to K_2SO_4 + 2CrO_2Cl_2 + 2BaSO_4 + 3H_2O` (chromyl chloride TEST) (C )`FeSO_4 + K_3[Fe(CN)_6]to K Fe^(II)[Fe^(III)(CN)_6]`(Turns bull's blue ) +`K_2SO_4` (D)`Cu(OH)_2+2NH_4OH+(NH_4)_2SO_4 to [Cu(NH_3)_4]SO_4` (Schwitezer's reagent) +`4H_2O` (E)`Co(NO_3)_2 +ZnO oversetDeltato CoZnO_3 or Co O.
