Infobox references. Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl 4. It is a non-flammable, dense, colourless liquid with a "sweet" chloroform -like odour that can be detected at low levels.
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.
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.
A solvent (from the Latin solvÅ, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are ...
As chloroform is a volatile organic compound, [18] it dissipates readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. Its half-life in air ranges from 55 to 620 days. Biodegradation in water and soil is slow.
Chemical bonding of water. Water (H2O) is a simple triatomic bent molecule with C 2v molecular symmetry and bond angle of 104.5° between the central oxygen atom and the hydrogen atoms. Despite being one of the simplest triatomic molecules, its chemical bonding scheme is nonetheless complex as many of its bonding properties such as bond angle ...

Proposed structure of an imidazolium-based ionic liquid. An ionic liquid(IL) is a saltin the liquidstate at ambient conditions.
Salt (chemistry) The crystal structure of sodium chloride, NaCl, a typical salt. The purple spheres represent sodium cations, Na +, and the green spheres represent chloride anions, Cl −. The yellow stipples show the electrostatic forces. In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively ...
