Earth's History

Some students are testing rock samples they collected. If you wanted to test these rocks for calcite, what would you put in the bottle and what would you expect to happen if calcite is there?

• Put water in the bottle; if there is calcite the rock will dissolve.

• Put salt water in the bottle; if there is calcite, the rock will turn a darker color.

• Put acid in the bottle; if there is calcite, the rock will fizz.

• Put liquid soap in the bottle; if there is calcite, the liquid will form a dome on the rock.
