Yellow chromate ions (cro4) react with hydrogen ions(2h) in acid to form orange dichromate ions ( if more acid is added to an equilibrium mixture will it become more orange or more yellow?asap

The solution will become more orange.

Explanation:

Start by writing the chemical equation for the equilibrium.

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.

i'm wiling to try and you : )
