The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.
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.
Its It is soluble in water, though less so than barium chloride, and its solubility decreases with increasing concentration of hydrochloric acid. Crystallization from aqueous solution gives the dihydrate RaCl 2 ·2H 2 O, isomorphous with its barium analog. [25] Radium bromide (RaBr 2) is also a colorless, luminous compound. [25]
All uranium chlorides react with water and air. Bromides and iodides of uranium are formed by direct reaction of, respectively, bromine and iodine with uranium or by adding UH 3 to those element's acids. [6] Known examples include: UBr 3, UBr 4, UI 3, and UI 4. UI 5 has never been prepared. Uranium oxyhalides are water-soluble and include UO 2 ...
222 Rn belongs to the radium and uranium-238 decay chain, and has a half-life of 3.8235 days. Its first four products (excluding marginal decay schemes ) are very short-lived, meaning that the corresponding disintegrations are indicative of the initial radon distribution.
Uranyl nitrate is a water-soluble yellow uranium salt with the formula UO 2 (NO 3) 2 · n H 2 O. The hexa-, tri-, and dihydrates are known. [3] The compound is mainly of interest because it is an intermediate in the preparation of nuclear fuels. In the nuclear industry, it is commonly referred to as yellow salt.
All uranium chlorides react with water and air. Bromides and iodides of uranium are formed by direct reaction of, respectively, bromine and iodine with uranium or by adding UH 3 to those element's acids. [107] Known examples include: UBr 3, UBr 4, UI 3, and UI 4. UI 5 has never been prepared. Uranium oxyhalides are water-soluble and include UO ...
Radium oxide (RaO) has not been characterized well past its existence, despite oxides being common compounds for the other alkaline earth metals. Radium hydroxide (Ra(OH) 2) is the most readily soluble among the alkaline earth hydroxides and is a stronger base than its barium congener, barium hydroxide. [3]
