  2. Carbonic acid - Wikipedia

    en.wikipedia.org/wiki/Carbonic_acid

    However, in the absence of water, it is quite stable at room temperature. [5] [6] The interconversion of carbon dioxide and carbonic acid is related to the breathing cycle of animals and the acidification of natural waters. [4] In biochemistry and physiology, the name "carbonic acid" is sometimes applied to aqueous solutions of carbon dioxide.

  3. Bicarbonate buffer system - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate_buffer_system

    Most of the carbonic acid then dissociates to bicarbonate and hydrogen ions. The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H 2 CO 3), bicarbonate ion (HCO − 3), and carbon dioxide (CO 2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper ...

  4. Carbon dioxide (data page) - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_(data_page)

    ‡ Second column of table indicates solubility at each given temperature in volume of CO 2 as it would be measured at 101.3 kPa and 0 °C per volume of water. The solubility is given for "pure water", i.e., water which contain only CO 2. This water is going to be acidic. For example, at 25 °C the pH of 3.9 is expected (see carbonic acid).

  5. Alkali metal - Wikipedia

    en.wikipedia.org/wiki/Alkali_metal

    The formation of an alkali metal nitride would consume the ionisation energy of the alkali metal (forming M + ions), the energy required to break the triple bond in N 2 and the formation of N 3− ions, and all the energy released from the formation of an alkali metal nitride is from the lattice energy of the alkali metal nitride.

  6. Surface properties of transition metal oxides - Wikipedia

    en.wikipedia.org/wiki/Surface_properties_of...

    Two promising methods for the description of the acidbase properties of metal oxides are Calorimetric measurements of adsorption enthalpies and Temperature Programmed desorption. [16] The measurement of the heat of adsorption of basic or acidic probe molecules can give a description of acidic and basic sites on metal oxide surfaces ...

  7. Acid–base homeostasis - Wikipedia

    en.wikipedia.org/wiki/Acidbase_homeostasis

    An acid-base diagram for human plasma, showing the effects on the plasma pH when P CO 2 in mmHg or Standard Base Excess (SBE) occur in excess or are deficient in the plasma [23] Acidbase imbalance occurs when a significant insult causes the blood pH to shift out of the normal range (7.32 to 7.42 [16]).

  8. Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal

    Reaction with acidic oxides. Alkaline earth metals reduce the nonmetal from its oxide. 2Mg + SiO 2 → 2MgO + Si 2Mg + CO 2 → 2MgO + C (in solid carbon dioxide) Reaction with acids. Mg + 2HCl → MgCl 2 + H 2 Be + 2HCl → BeCl 2 + H 2. Reaction with bases. Be exhibits amphoteric properties. It dissolves in concentrated sodium hydroxide.

  9. 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.
