Question

Aqueous solutions of carbon dioxide turn blue litmus paper red but don’t affect red litmus paper.

1) Write the balanced molecular equation that explains what happens to carbon dioxide when it is mixed with water that causes it to affect blue litmus paper.

Based on the behavior of the other oxides above, how do you think aqueous solutions of sulfur trioxide behave?

2) Write the balanced molecular equation that explains what happens to sulfur trioxode when it is mixed with water and describe how it would affect red and blue litmus papers.

Calcium oxide, magnesium oxide, and aluminum oxide are all insoluble ionic compounds but they each react with HCl and seem to “dissolve” (they don’t actually become soluble; they turn into something that is soluble).

3) Write the balanced molecular equation for each of these reactions.
