A student is studying the equilibriumrepresented by the equation :
2CrO42-(aq, yellow) +2H3O+(aq) Cr2O72-(aq, orange) +3H2O(l)
The mixture obtained by the student is yellow.
Describe the color change the student should observe in terms of LeChatalier’s Principle after adding solidNa2CrO4 to the above chemical equation andafter having added HCl previously. Recall that Na2CrO4 dissolves in waterand dissociates into Na+ andCrO42- ions.
