Following steps are involved in manufacturing of potassium dichromate :
Sum of Oxidation number of Cr in X, Y and Z is____________
Answer:
15
Solution:
X (Chromite ore): The formula is FeCr₂O₄, where the oxidation state of Chromium is +3. Y (Solution): Fusion with sodium carbonate in air yields sodium chromate (Na₂CrO₄), where Cr is +6.
Z (Solution): Adding sulfuric acid converts the chromate to sodium dichromate (Na₂Cr₂O₇), where Cr is +6.
Calculation: The sum of the oxidation numbers is .
