Scientist Sarah Hardy says: "Based on the research we have so far, I believe that if we combine chalk with our acidic rain (vinegar) a chemical reaction will occur in which the chalk will begin to bubble, and slowly erode and crumble onto Mr. Casey’s statue. This is due to the two reactants, limestone and acidic rain (vinegar or orange juice) creating the product of CO2. I don’t believe that Mr. Casey’s statue would be safe by a limestone cliff."
Scientist Lauryn Blottin says: "My hypothesis is that if we mix chalk with vinegar, then the chalk will dissolve and fall on Mr Casey's statue. Because chalk is a calcium carbonate, when mixed with an acetic acid, its dissolves and forms, Co2 , calcium salts and water, which will erode and wash away and make his statue fall , but not in an instant."
Scientist Blake Jeffreys says: "I think that if we mix the chalk with orange juice, then it will create about the same reaction as it would if you used vinegar. However, I believe the lemon would create a smaller reaction due to its smaller pH. I predict that baking soda would bring the chalk back to its original properties. I also agree with Sarah and Lauryn, that the statue would be better off somewhere else other than beneath the limestone cliff.
