Answer:
The solution will become more orange.
Explanation:
Start by writing the chemical equation for the equilibrium.
[tex]\underbrace{\hbox{2CrO$_{4}^{2-}$}}_{\hbox{yellow}} + \text{2H}^{+} \rightleftharpoons \underbrace{\hbox{Cr$_{2}$O$_{7}^{2-}$}}_{\hbox{orange}} + \text{H}_{2}\text{O}[/tex]
Le Châtelier’s Principle states that if you apply a stress to a system at equilibrium the system will respond in a way that will reduce the stress.
In this case, the stress is the addition of H⁺ ions.
The system will respond by trying to get rid of the added H⁺ ions.
Thus, the position of equilibrium will move to the right.
More Cr₂O₇²⁻ ions will form, and the solution will become more orange.
