  3. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  4. Bjerrum plot - Wikipedia

    en.wikipedia.org/wiki/Bjerrum_plot

    Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...

  5. Carbonic acid - Wikipedia

    en.wikipedia.org/wiki/Carbonic_acid

    In even a slight presence of water, carbonic acid dehydrates to carbon dioxide and water, which then catalyzes further decomposition. [6] For this reason, carbon dioxide can be considered the carbonic acid anhydride. The hydration equilibrium constant at 25 °C is [H 2 CO 3]/[CO 2] ≈ 1.7×10 −3 in pure water [12] and ≈ 1.2×10 −3 in ...

    Crystal structure of calcite. Calcium carbonate is a chemical compound with the chemical formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skeletons and pearls.

  7. Calcium chloride - Wikipedia

    en.wikipedia.org/wiki/Calcium_chloride

    It is a white crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl 2 ·nH 2 O, where n = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and dust ...

  9. Alkali–carbonate reaction - Wikipedia

    en.wikipedia.org/wiki/Alkali–carbonate_reaction

    The alkali–carbonate reaction is an alteration process first suspected in the 1950s in Canada for the degradation of concrete containing dolomite aggregates. [ 1 ] [ 2 ] Alkali from the cement might react with the dolomite crystals present in the aggregate inducing the production of brucite , (MgOH) 2 , and calcite (CaCO 3 ).
