Question

multiple choice question given the right conditions, ______ carbonate in tests will dissolve in ocean water. the depth at which this dissolution first begins is called the lysocline. options: calcium, sodium, magnesium

Explanation:

In oceanography and marine chemistry, calcium carbonate (e.g., in the tests of organisms like foraminifera) is known to dissolve in ocean water at certain depths (the lysocline). Sodium carbonate and magnesium carbonate do not have this specific dissolution behavior related to the lysocline in the context of marine organism tests.

Answer:

A. calcium
