Potassium carbonate is the inorganic compound with the formula K 2 C O 3.It is a white salt, which is soluble in water and forms a strongly alkaline solution. It is deliquescent, often appearing as a damp or wet solid.
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.
An alternative way of producing potassium nitrate without a by-product of ammonia is to combine ammonium nitrate, found in instant ice packs, [30] and potassium chloride, easily obtained as a sodium-free salt substitute. NH 4 NO 3 + KCl → NH 4 Cl + KNO 3. Potassium nitrate can also be produced by neutralizing nitric acid with potassium ...
It can substitute for baking soda (sodium bicarbonate) for those with a low-sodium diet, [4] and it is an ingredient in low-sodium baking powders. [5] [6] As an inexpensive, nontoxic base, it is widely used in diverse application to regulate pH or as a reagent. Examples include as buffering agent in medications, an additive in winemaking.

Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid with the molecular formula K 3 C 6 H 5 O 7.It is a white, hygroscopic crystalline powder. It is odorless with a saline taste.
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
Potassium acetate (as a substitute for calcium chloride or magnesium chloride) can be used as a deicer to remove ice or prevent its formation. It offers the advantage of being less aggressive on soils and much less corrosive: [5] for this reason, it is preferred for airport runways although it is more expensive.
