which is the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid when doing fieldwork? to wash rock samples to make them easier to study to wear away large areas of rock to see what is underneath to test for the presence of carbonate minerals in a rock to use as an emergency eyewash in case rock dust gets in the eyes done
Answer
# Brief Explanations:
Carbonate minerals react with hydrochloric acid to produce carbon - dioxide gas, which can be easily observed as fizzing. This reaction is used by geologists to test for the presence of carbonate minerals in rocks. Washing with HCl is not a common way to clean samples, wearing away large rock areas is not practical with a small dropper bottle, and HCl is a strong acid and not suitable for eye - wash.
# Answer:
to test for the presence of carbonate minerals in a rock
