It is very insoluble in water, but is soluble in acids: 2 BaCrO 4 + 2 H + → 2 Ba 2+ + Cr 2 O 7 2− + H 2 O K sp = [Ba 2+][CrO 4 2−] = 2.1 × 10 −10. It can react with barium hydroxide in the presence of sodium azide to create barium chromate(V). The reaction releases oxygen and water.
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.
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.
Some hydroxides of non-metallic elements are soluble in water; they are not included in the following table. Examples cited by Baes and Mesmer (p. 413) include hydroxides of Gallium(III), Indium(III), Thallium(III), Arsenic(III), Antimony(III) and Bismuth(III). Most hydroxides of transition metals are classified as being "insoluble" in water.
Chromate and dichromate salts of heavy metals, lanthanides and alkaline earth metals are only very slightly soluble in water and are thus used as pigments. The lead-containing pigment chrome yellow was used for a very long time before environmental regulations discouraged its use. [ 7 ]
OREBRO, Sweden (Reuters) -Sweden's right-wing government said on Friday it would seek to tighten gun laws in the wake of the country's deadliest mass shooting at an adult education centre where ...
Radium forms much the same insoluble salts as its lighter congener barium: it forms the insoluble sulfate (RaSO 4, the most insoluble known sulfate), chromate (RaCrO 4), carbonate (RaCO 3), iodate (Ra(IO 3) 2), tetrafluoroberyllate (RaBeF 4), and nitrate (Ra(NO 3) 2). With the exception of the carbonate, all of these are less soluble in water ...
