  2. Potassium - Wikipedia

    en.wikipedia.org/wiki/Potassium

    Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) ... (which combines with anions to form salts). In nature, potassium occurs only in ionic salts.

  3. Anion gap - Wikipedia

    en.wikipedia.org/wiki/Anion_gap

    The anion gap is representative of how many ions are not accounted for by the lab measurements used in the calculation. These "unmeasured" ions are mostly anions, which is why the value is called the "anion gap." [3] By definition, only the cations sodium (Na +) and potassium (K +) and the anions chloride (Cl −) and bicarbonate (HCO −

  4. Potassium in biology - Wikipedia

    en.wikipedia.org/wiki/Potassium_in_biology

    Potassium is the major cation (K +, a positive ion) inside animal cells, while sodium (Na +) is the major cation outside animal cells.The difference between the concentrations of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential.

  5. Potassium cyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_cyanide

    Potassium cyanide is a compound with the formula KCN. It is a colorless salt, similar in appearance to sugar , that is highly soluble in water. Most KCN is used in gold mining , organic synthesis , and electroplating .

  6. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    A cation is a positively charged ion with fewer electrons than protons [2] (e.g. K + (potassium ion)) while an anion is a negatively charged ion with more electrons than protons. [ 3 ] (e.g. Cl − (chloride ion) and OH − (hydroxide ion)).

  7. Potassium permanganate - Wikipedia

    en.wikipedia.org/wiki/Potassium_permanganate

    Potassium permanganate is an inorganic compound with the chemical formula KMnO 4. It is a purplish-black crystalline salt, ... is caused by its permanganate anion, ...

  8. Tetrafluoroborate - Wikipedia

    en.wikipedia.org/wiki/Tetrafluoroborate

    The structure of the tetrafluoroborate anion, BF − 4. Tetrafluoroborate is the anion BF − 4. This tetrahedral species is isoelectronic with tetrafluoroberyllate (BeF 2− 4), tetrafluoromethane (CF 4), and tetrafluoroammonium (NF + 4) and is valence isoelectronic with many stable and important species including the perchlorate anion, ClO −

  9. Potassium carbonate - Wikipedia

    en.wikipedia.org/wiki/Potassium_carbonate

    Potassium carbonate is mainly used in the production of soap and glass. [3] Commonly, it can be found as the result of leakage of alkaline batteries. [4] Potassium carbonate is a potassium salt of carbonic acid. This salt consists of potassium cations K + and carbonate anions CO 2− 3, and is therefore an alkali metal carbonate.
