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.
Some silver oxide powder.. Silver is a relatively unreactive metal, although it can form several compounds. The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO 3); +2 (highly oxidising; for example, silver(II) fluoride, AgF 2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III ...

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.
Normal bases are also nucleophiles, but often chemists seek the proton-removing ability of a base without any other functions. Typical non-nucleophilic bases are bulky, such that protons can attach to the basic center but alkylation and complexation is inhibited.
Silver carbonate is the chemical compound with the formula Ag 2 C O 3. This salt is yellow but typical samples are grayish due to the presence of elemental silver . It is poorly soluble in water, like most transition metal carbonates .
Silver vase, c. 2400 BC Karashamb silver goblet, 23rd–22nd century BC. Silver was known in prehistoric times: [63] the three metals of group 11, copper, silver, and gold, occur in the elemental form in nature and were probably used as the first primitive forms of money as opposed to simple bartering. [64]
The alkaline earth metals are all silver-colored and soft, and have relatively low densities, melting points, and boiling points. In chemical terms, all of the alkaline earth metals react with the halogens to form the alkaline earth metal halides , all of which are ionic crystalline compounds (except for beryllium chloride , beryllium bromide ...
