Being a solid highly soluble in water (545 g/L at 25 °C), [2] urea is much easier and safer to handle and store than the more irritant, caustic and hazardous ammonia (NH 3), so it is the reactant of choice. Trucks and cars using these catalytic converters need to carry a supply of diesel exhaust fluid, also sold as AdBlue, a solution of urea ...
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.
Urea phosphate is a 1:1 combination of urea and phosphoric acid that is used as a fertilizer. It has an NPK formula of 17-44-0, [ 1 ] and is soluble in water, producing a strongly acidic solution. Urea phosphate is available in fertilizer vendor bags that carry a UP signet on the packaging.
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.
Biotin, a water-soluble B vitamin, is a bicyclic urea.. In chemistry, ureas are a class of organic compounds with the formula (R 2 N) 2 CO where R = H, alkyl, aryl, etc. Thus, in addition to describing the specific chemical compound urea ((H 2 N) 2 CO), urea is the name of a functional group that is found in many compounds and materials of both practical and theoretical interest.
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.
Isobutylidenediurea (abbreviated IBDU) is an organic compound with the formula (CH 3) 2 CHCH{NHC(O)NH 2} 2.It is a derivative of urea (OC(NH 2) 2), which itself is highly soluble in water, but IBDU is not.
Thiourea (/ ˌ θ aɪ. oʊ j ʊəˈr iː. ə,-ˈ jʊər i-/) [2] [3]}} is an organosulfur compound with the formula SC(NH 2) 2 and the structure H 2 N−C(=S)−NH 2. It is structurally similar to urea (H 2 N−C(=O)−NH 2), with the oxygen atom replaced by sulfur atom (as implied by the thio-prefix). The properties of urea and thiourea differ ...
