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.

1-Iodohexane is a chemical compound from the group of aliphatic saturated halogenated hydrocarbons. The chemical formula is CH 3 (CH 2 ) 5 I . [ 2 ] [ 3 ] It is a colorless liquid.
2 I 2 + 5 SbF 5 2 I 2 Sb 2 F 11 + SbF 3. The salt I 2 Sb 2 F 11 is dark blue, and the blue tantalum analogue I 2 Ta 2 F 11 is also known. Whereas the I–I bond length in I 2 is 267 pm, that in I + 2 is only 256 pm as the missing electron in the latter has been removed from an antibonding orbital, making the bond stronger and hence shorter.
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
These iodine compounds are hypervalent because the iodine atom formally contains in its valence shell more than the 8 electrons required for the octet rule. Hypervalent iodine oxyanions are known for oxidation states +1, +3, +5, and +7; organic analogues of these moieties are known for each oxidation state except +7.
[1] In the chemical and pharmaceutical sciences, both phases usually are solvents. [2] Most commonly, one of the solvents is water, while the second is hydrophobic, such as 1-octanol. [3] Hence the partition coefficient measures how hydrophilic ("water-loving") or hydrophobic ("water-fearing") a chemical substance is.
2,5-Hexanedione (Acetonylacetone) is an aliphatic diketone. It is a colorless liquid. [ 1 ] In humans, it is a toxic metabolite of hexane and of 2-hexanone .
