You added sodium sulfate solution to well A1 and observed a color change. Select the answer that best explains how your observations tell you which way the equilibrium is shifting. (Well A1 has 10 drops of NaHSO4 before sodium sulfate was added)

a.) Addition of the sulfate ion causes the equilibrium to shift to the right (to the product side), consuming both sulfate and acid ions. The decrease in the acid concentration results in some of the thymol blue changing to yellow, which is observed as the red solution turns orange.

b.)Addition of the sulfate ion causes the equilibrium to shift to the left (to the reactant side), consuming both sulfate and acid ions. The decrease in the acid concentration results in some of the thymol blue changing to yellow, which is observed as the red solution turns orange.

c.) Addition of the sulfate ion causes the equilibrium to shift to the left (to the reactant side), consuming both sulfate and acid ions. The increase in the acid concentration results in some of the thymol blue changing to yellow, which is observed as the red solution turns orange.

d.)Addition of the sulfate ion causes the equilibrium to shift to the right (to the product side), consuming both sulfate and acid ions. The increase in the acid concentration results in some of the thymol blue changing to yellow, which is observed as the red solution turns orange.
