To the right

Explanation:

The addition of an acid simply mean s we are having more hydrogen ions being supplied to the system. Hence, we are increasing the concentration of the hydrogen ions.

As the hydrogen ions are getting more concentrated, this is synonymous with getting more reactant added to the system. And as such, there is a greater activity for the bromophenol blue and thus the equilibrium shifts to the right.

According to Le Chatelier's principle, the system would have to respond to this constraint by adjusting the equilibrium position to the right.
