This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Paracetamol, [a] or acetaminophen, [b] is a non-opioid analgesic and antipyretic agent used to treat fever and mild to moderate pain. [13] [14] [15] It is a widely available over-the-counter drug sold under various brand names, including Tylenol and Panadol.
Positive solvatochromism corresponds to a bathochromic shift (or red shift) with increasing solvent polarity. An example of positive solvatochromism is provided by 4,4'-bis(dimethylamino)fuchsone, which is orange in toluene, red in acetone. The main value of the concept of solvatochromism is the context it provides to predict colors of solutions.

[10]: 280–4 Hence, a single experiment can be used to measure the logarithms of the partition coefficient (log P) giving the distribution of molecules that are primarily neutral in charge, as well as the distribution coefficient (log D) of all forms of the molecule over a pH range, e.g., between 2 and 12.
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 conventional units for the solubility parameter are (calories per cm 3) 1/2, or cal 1/2 cm −3/2.The SI units are J 1/2 m −3/2, equivalent to the pascal 1/2. 1 calorie is equal to 4.184 J.
