Francium hydroxide is a hypothetical inorganic compound with a chemical formula Fr O H. It is a hydroxide of francium . It probably can be produced by reacting francium metal with water : [ 1 ]
Francium chloride is a radioactive chemical compound with the formula FrCl. It is a salt predicted to be a white solid and is soluble in water.
Francium nitrate, sulfate, hydroxide, carbonate, acetate, and oxalate are all soluble in water, while the iodate, picrate, tartrate, chloroplatinate, and silicotungstate are insoluble. The insoluble compounds are used to extract francium from other radioactive products, such as zirconium , niobium , molybdenum , tin , and antimony , using the ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Francium-223 also has a shorter half-life than the longest-lived isotope of each synthetic element up to and including element 105, dubnium. [8] Francium is an alkali metal whose chemical properties mostly resemble those of caesium. [8] A heavy element with a single valence electron, [9] it has the highest equivalent weight of any element. [8]
Water molecules are omitted in this diagram. The model is defined in terms of a list of those complex species which are present in solutions in significant amounts. In the present context the complex species have the general formula [M p O q (OH) r] n±. where p, q and r define the stoichiometry of the species and n± gives the electrical ...
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.
Francium oxide – Fr 2 O; Francium chloride – FrCl; Francium bromide – FrBr; Francium iodide – FrI; Francium carbonate – Fr 2 CO 3; Francium hydroxide – FrOH; Francium sulfate – Fr 2 SO 4
