For acetic acid, K a = 1.8 x 10 −5, so pK a is about 5. A higher K a corresponds to a stronger acid (an acid that is more dissociated at equilibrium). The form pK a is often used because it provides a convenient logarithmic scale, where a lower pK a corresponds to a stronger acid.
Potassium carbonate (K 2 CO 3 or potash) is used in the manufacture of glass, soap, color TV tubes, fluorescent lamps, textile dyes and pigments. [75] Potassium permanganate (KMnO 4) is an oxidizing, bleaching and purification substance and is used for production of saccharin. Potassium chlorate (KClO 3) is added to matches and explosives.
K is the sign of potassium on the Periodic Table of Elements. However: "Fun fact: Minerals are included, vitamins are not. So, only potassium is represented, not vitamin K," Dr. Durham says.
In chemistry, biochemistry, and pharmacology, a dissociation constant (K D) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions.
Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues.

The sodium–potassium pump a critical enzyme for regulating sodium and potassium levels in cells. Potassium is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. [1] [2] Potassium is necessary for the function of all living cells and is thus present in all plant and ...

Potassium chloride is inexpensively available and is rarely prepared intentionally in the laboratory. It can be generated by treating potassium hydroxide (or other potassium bases) with hydrochloric acid: + + This conversion is an acid-base neutralization reaction. The resulting salt can then be purified by recrystallization.
