Most ionic compounds are soluble in water because the electrostatic forces of the polar water molecules are stronger than the electrostatic forces keeping the ions together. There are several exceptions, however, where t... More »

Carbon tetrachloride has very low solubility in water, with 1,160 milligrams soluble in 1 liter of water at 25 degrees Celsius. As temperature decreases, its solubility in water drops further, and 800 milligrams of carbo... More »

KCl, potassium chloride, is a compound made up of the alkali metal potassium and chlorine, and it is soluble in water. In an aqueous solution, KCl separates into K+ and Cl- ions. More »

Hydrocarbons do not dissolve in water because they are nonpolar compounds and water is a polar solvent. The general solubility rule is "like dissolves like," meaning polar solvents dissolve polar solutes and nonpolar sol... More »

To name ionic compounds, first find the cation and the anion. Next, name the ionic compound by writing the name of the cation followed by the name of the anion. More » Science Chemistry Atoms & Molecules

The naming of ionic compounds requires correct identification of the cation and anion species present. In certain cases, the charge of the ion is important for accurate naming. More »

Ionic radius trends are seen within a group in the periodic table, where the radius gets bigger as one moves down a group and across a period, where the radius decreases among positive ions and increases among negative i... More »
