  2. Calcium carbonate - Wikipedia

    en.wikipedia.org/wiki/Calcium_carbonate

    As such water percolates through calcium carbonate rock, the CaCO 3 dissolves according to one of the trends above. When that same water then emerges from the tap, in time it comes into equilibrium with CO 2 levels in the air by outgassing its excess CO 2. The calcium carbonate becomes less soluble as a result, and the excess precipitates as ...

  3. Calcium bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Calcium_bicarbonate

    As water containing carbon dioxide (including extra CO 2 acquired from soil organisms) passes through limestone or other calcium carbonate-containing minerals, it dissolves part of the calcium carbonate, hence becomes richer in bicarbonate. As the groundwater enters the cave, the excess carbon dioxide is released from the solution of the ...

  4. Carbonate compensation depth - Wikipedia

    en.wikipedia.org/wiki/Carbonate_compensation_depth

    The exact value of the CCD depends on the solubility of calcium carbonate which is determined by temperature, pressure and the chemical composition of the water – in particular the amount of dissolved CO 2 in the water. Calcium carbonate is more soluble at lower temperatures and at higher pressures.

  5. Solubility - Wikipedia

    en.wikipedia.org/wiki/Solubility

    The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.

  7. Alkali salt - Wikipedia

    en.wikipedia.org/wiki/Alkali_salt

    The chloride from the hydrochloric acid in sodium chloride does not hydrolyze, though, so sodium chloride is not basic. The difference between a basic salt and an alkali is that an alkali is the soluble hydroxide compound of an alkali metal or an alkaline earth metal. A basic salt is any salt that hydrolyzes to form a basic solution.
