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.
Sodium hydroxide can be used for the base-driven hydrolysis of esters (also called saponification), amides and alkyl halides. [16] However, the limited solubility of sodium hydroxide in organic solvents means that the more soluble potassium hydroxide (KOH) is often preferred. Touching a sodium hydroxide solution with bare hands, while not ...
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.
Ethanol is a neutral molecule and the pH of a solution of ethanol in water is nearly 7.00. Ethanol can be quantitatively converted to its conjugate base, the ethoxide ion (CH 3 CH 2 O −), by reaction with an alkali metal such as sodium: [79] 2 CH 3 CH 2 OH + 2 Na → 2 CH 3 CH 2 ONa + H 2. or a very strong base such as sodium hydride: CH 3 CH ...
Solubility in ethanol: 5 g/100 g (0 °C) 11.3 g/100 g (25 °C) ... followed by neutralization with sodium hydroxide or calcium hydroxide. Other derivative uses
This process requires dispersing medium, monomers, stabilizing agents, and initiators. Next, the polymers were swollen in ethanol and hydrolyzed in an aqueous solution of sodium hydroxide. Finally, water-soluble sodium polyacrylates were obtained by washing and drying the hydrolyzed resultant.
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.
A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook. Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] and the liquid sodium acetate dissolves in the released water of crystallization.
