Which type of scientist makes use of the reaction of carbonates with acids?

Explanation:

Geologists - acid test used to determine if a sample is a carbonate (Geology fizz test)

Hydrochloric acid is the most common acid used among geologists to test whether a rock has any calcite content. In this reaction, the calcium carbonate reacts with the acid and produces carbon dioxide gas, water, and calcium chloride

Pharmaceutical scientists and physicians - carbonates are often used as antacids. These antacids are used to reduce the acid reflux in the gut. Antacids are then taken to reduce the pH where CO2 is given off.
