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

Respuesta :

Answer:

C, to test for the presence of carbonate minerals in a rock

Explanation:

I did this a few weeks ago on Edge. Hydrochloric acid isn't for rock washing, they wouldn't use it to wear away rocks since it'd ruin the sample I think, and you will go blind if you put it in your eyes

Geologist carry dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.

Test for carbonate minerals

Hydrochloric acid is used to test for presence of carbon iv oxide in compounds.

When hydrochloric acid reacts with carbonates, it produces effervescent due to the prensence of carbon iv oxides in the compound.

Geologist will use this acid (hydrochloric acid) to check if the rock sample contains carbonate minerals.

Thus, the best reason that a geologist might carry a small dropper bottle filled with hydrochloric acid when doing fieldwork is to test for the presence of carbonate minerals in a rock.
