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. Carbonate minerals react with hydrochloric acid to produce carbon - dioxide gas, which can be observed as fizzing or bubbling. Washing rock samples with acid is not a common practice as it can alter the sample. Wearing away large areas of rock with a small dropper bottle is not practical. Hydrochloric acid is a strong acid and cannot be used as an eyewash.
# Answer:
to test for the presence of carbonate minerals in a rock
