Carbon dioxide and water readily combine to form carbonic acid. The change in pH as the acid dissociates can be demonstrated with an indicator dye that changes color at a particular pH. Following this lab in which the color of the solution was observed to change, one lab group forgot to dump the beakers at the end of the lab period. The next day would you expect the beakers to look the same as

they did after being bubbled with CO2? If not, explain in terms of reversible reactions and equilibrium disturbance. What will be an ideal response?
