Both NaCl and CaCO3 are highly soluble in water.

NaCl is soluble in water but CaCO3 is not. Hence, concentration of CaCO3 in the oceans

through weathering is an untenable hypothesis.

(c) The solubility of CaCO3 in water is pH dependent and is enhanced by acidic atmospheric gases.

Hence, CaCO3 may be leached into water during weathering.

(d) NaCl and CaCO3 are igneous rocks and have crystallized as such during the slow cooling

process when the earth was born. Hence, the ocean postulates is baseless.
