Given that the Ka of benzoic acid is 6.3 x 10-5 , calculate the pH at the following points when 0.080 M sodium hydroxide is added to 10.0 mL of 0.052 M benzoic acid: At the equivalence point After 1.5 mL of excess base have been added

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

it's filtration, but this is an assumption so my apologies if i got this
