When solid sodium bisulfate is added to a solution of sodium bisulfate and thymol blue indicator, which way would the equilibrium shift?

Sodium bisulphate + thymol blue -----------> product

According to the Le Chatlier's principle, any change to a system at equilibrium will adjust to compensate for that change.Le Châtelier's principle states that if the system is changed in a way that increases the concentration of one of the reacting species, it must favor the reaction in which that species is consumed. In other words, if there is an increase in products, the reaction quotient, Qc, is increased, making it greater than the equilibrium constant, Kc.

According to Le Châtelier, the position of equilibrium will move in such a way as to counteract the change. In this case, the equilibrium position will move so that the concentration of A decreases again by reacting it with B to form more C and D. The equilibrium moves to the right

So, shift towards products takes place.
