Explain the color change that occurred when water was added in Step 2. (Consider how a change in [Cl] and [H₂O] will shift Reaction 7.) b. the diluted solution was heated. (How would Reaction 7 shift if K, went up? How did increasing the temperature affect the value of K? What is the sign of AH in Reaction 7?)
