  2. 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.

  3. Solubility table - Wikipedia

    en.wikipedia.org/wiki/Solubility_table

    The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.

  4. 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 ...

    Leafy greens—like spinach, kale, collards, lettuce and cabbage—deliver fiber and water, meaning they'll help keep you hydrated and fill you up with lots of nutrients in a few calories.

  6. Solubility - Wikipedia

    en.wikipedia.org/wiki/Solubility

    A few, such as calcium sulfate and cerium(III) sulfate, become less soluble in water as temperature increases (ΔH < 0). [15] This is also the case for calcium hydroxide (portlandite), whose solubility at 70 °C is about half of its value at 25 °C. The dissolution of calcium hydroxide in water is also an exothermic process (ΔH < 0

  7. Carbonate hardness - Wikipedia

    en.wikipedia.org/wiki/Carbonate_hardness

    An aqueous solution containing 120 mg NaHCO 3 (baking soda) per litre of water will contain 1.4285 mmol/l of bicarbonate, since the molar mass of baking soda is 84.007 g/mol. This is equivalent in carbonate hardness to a solution containing 0.71423 mmol/L of (calcium) carbonate, or 71.485 mg/L of calcium carbonate (molar mass 100.09 g/mol).

  9. Ammonium carbonate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_carbonate

    It is prepared by the sublimation of a mixture of ammonium sulfate and calcium carbonate and occurs as a white powder or a hard, white or translucent mass. [4] It acts as a heat activated leavening agent and breaks down into carbon dioxide (leavening), ammonia (which needs to dissipate) and water.
