  2. Carbonic acid - Wikipedia

    en.wikipedia.org/wiki/Carbonic_acid

    Carbonic acid is a chemical compound with the chemical formula H 2 C O 3.The molecule rapidly converts to water and carbon dioxide in the presence of water. However, in the absence of water, it is quite stable at room temperature.

  3. Bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate

    The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 O ⇌ HCO −

  5. Carbonate - Wikipedia

    en.wikipedia.org/wiki/Carbonate

    A carbonate is a salt of carbonic acid, (H 2 CO 3), [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3.The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group O=C(−O−) 2.

  6. Bicarbonate buffer system - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate_buffer_system

    As with any buffer system, the pH is balanced by the presence of both a weak acid (for example, H 2 CO 3) and its conjugate base (for example, HCO − 3) so that any excess acid or base introduced to the system is neutralized.

  7. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    The charge number equals the electric charge (q, in coulombs) divided by the elementary charge: z = q/e. Atomic numbers (Z) are a special case of charge numbers, referring to the charge number of an atomic nucleus, as opposed to the net charge of an atom or ion. The charge numbers for ions (and also subatomic particles) are written in ...

  9. Oxyanion - Wikipedia

    en.wikipedia.org/wiki/Oxyanion

    HPO 2− 3 (phosphite ion) structure Sulfuric acid molecule. The extent of protonation in aqueous solution will depend on the acid dissociation constants and pH. For example, AMP (adenosine monophosphate) has a pK a value of 6.21, [8] so at pH 7 it will be about 10% protonated. Charge neutralization is an important factor in these protonation ...
