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.
Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow salt. [4] It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium.
The most dangerous form of occupational exposure to cadmium is inhalation of fine dust and fumes, or ingestion of highly soluble cadmium compounds. [9] Inhalation of cadmium fumes can result initially in metal fume fever, but may progress to chemical pneumonitis, pulmonary edema, and death. [76] Cadmium is also an environmental hazard.
Cadmium bromide is prepared by heating cadmium with bromine vapor. [2] The tetrahydrate has been obtained by crystallization of the dibromide from aqueous solution. At 3.04 g/cm 3, it is much less dense than the anhydrous material. According to X-ray crystallography, the tetrahydrate is a polymer of CdBr 2 (H 2 O) 2 with bridging bromide ligands.
The groom disagreed with his wife, countering that his friend was "just joking." "But I don’t find anything funny about that," the bride insisted.
Good Samaritans alerted the boy’s mother and chased Monsalve down the street, forcing her to release the toddler. They then called the police, who found her nearby.
The result: 1 liter of water can dissolve 1.34 × 10 −5 moles of AgCl at room temperature. Compared with other salts, AgCl is poorly soluble in water. For instance, table salt (NaCl) has a much higher K sp = 36 and is, therefore, more soluble. The following table gives an overview of solubility rules for various ionic compounds.
