Question

In the following reactions the sum of the total number of atoms in one molecule of (A),(B) & (C) is

NaCl+K2Cr2O7+H2SO4(A)+sideproducts(A)+NaOH(B)+sideproducts(B)+H2SO4(dil.)+H2O2(C)+sideproducts

Solution

Identification of the reactants:

NaClK2Cr2O7/Conc.H2SO4CrO2Cl2NaOHNa2CrO4+NaClNa2CrO4Dil.H2SO4Na2Cr2O7Dil.H2O2CrO5(A)=CrO2Cl2,(B)=Na2CrO4and(C)=CrO5

Therefore, the identified molecules are: (A)=CrO2Cl2,(B)=Na2CrO4and(C)=CrO5.
