which is the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid when doing fieldwork?\n to wash rock samples to make them easier to study\n to wear away large areas of rock to see what is underneath\n to test for the presence of carbonate minerals in a rock\n to use as an emergency eyewash in case rock dust gets in the eyes
Answer
# Brief Explanations:
Geologists use hydrochloric acid to test for carbonate minerals. Carbonates react with hydrochloric acid to produce carbon - dioxide gas, which can be easily observed as fizzing or bubbling. Washing rock samples with it is not a common practice as it can alter the samples. Wearing away large areas of rock is not practical or safe with a small dropper bottle. Hydrochloric acid is a strong acid and is not used as an eyewash.
# Answer:
to test for the presence of carbonate minerals in a rock
