The sedimentary rock that forms calcium carbonate and fizzes in acid is limestone.

Here's why:

* Calcium Carbonate: Limestone is primarily composed of calcium carbonate (CaCO3).

* Fizzing in Acid: When acid (like hydrochloric acid) is applied to limestone, it reacts with the calcium carbonate, producing carbon dioxide gas, which causes the fizzing.
