Chromium sulfate is an inorganic compound used as a tanning agent for leather manufacturing. It is produced after the reduction of potassium dichromate. The potassium dichromate is treated with 80% aqueous sulfuric acid solution and 20% excess H2O2 by the following reaction: K2Cr2O7 + 4 H2SO4 + 3 H2O2 à K2SO4 + Cr2(SO4)3 + 7 H2O + 3 O2 Analysis of the product mixture shows 40.21% Cr2(SO4)3, 4.11 % K2Cr2O7, 23.21% H2O. On a basis of 1000 kg of product mixture, determine the following: (a) Limiting reactant and excess reactants (b) % Excess of ER (c) Degree of completion (d) Illustrate The Law of Conservation of Mass

Question
Chromium sulfate is an inorganic compound used as a tanning agent for leather manufacturing. It is produced after the reduction of potassium dichromate. The potassium dichromate is treated with 80% aqueous sulfuric acid solution and 20% excess H2O2 by the following reaction:
K2Cr2O7 + 4 H2SO4 + 3 H2O2 à K2SO4 + Cr2(SO4)3 + 7 H2O + 3 O2
Analysis of the product mixture shows 40.21% Cr2(SO4)3, 4.11 % K2Cr2O7, 23.21% H2O. On a basis of 1000 kg of product mixture, determine the following:
(a) Limiting reactant and excess reactants
(b) % Excess of ER
(c) Degree of completion
(d) Illustrate The Law of Conservation of Mass
(e) Complete mass composition of product mixture
