The typical rule for dissolving substances in one another is that substances most readily dissolve other substances with similar bonds. Alkanes are nonpolar because they have mostly nonpolar bonds. On the other hand, ionic compounds have ionic bonds, which are extremely polar. Therefore, because the difference in bond type, ionic compounds do not dissolve in any alkane.
No. Water is a largely covalent compound that spontaneously ionizes only to give concentrations of 10-7 molar for each of hydrogen and hydroxide ions. However water also has a high dielectric constant and for that reason can dissolve many ionic compounds. Water can also dissolve sufficiently polar organic compounds, such as sugar, with little or no trace of ionic character.
Water is a better solvent for sodium chromate because sodium chromate is highly soluble in water due to its ionic nature. Butyl alcohol, being an organic solvent, may have limited solubility for sodium chromate.
Water, (h2o) is a polar compound, wherein it has a magnetic charge. This charge attracts an opposite charge such as salt and decouples the sodium chloride ion.
Potassium chloride will be more soluble in water because it is an ionic compound and water is a polar solvent, which can effectively dissolve ionic compounds due to opposite charges attracting each other. Isopropanol is a less polar solvent compared to water, so the solubility of potassium chloride in isopropanol will be lower.
Water is a polar molecule, and therefore dissolves other polar substances and many ionic compounds because of its partially positive hydrogen end and its partially negative oxygen end. However, petrol is a nonpolar substance and only dissolves other nonpolar substances.
Nonpolar solvents, such as hexane and benzene, do not dissolve ionic compounds because they lack the ability to dissociate the ions due to their nonpolar nature. Ionic compounds require polar solvents, such as water or alcohols, to dissolve and dissociate into their constituent ions.
CCl4 is a non polar solvent and therefore dissole ionic compounds
Ionic compounds typically do not dissolve well in organic solvents because organic solvents are nonpolar and ionic compounds are held together by strong electrostatic forces between positive and negative ions. These strong forces are not easily disrupted by the weak Van der Waals forces present in organic solvents, making it difficult for ionic compounds to dissolve.
It isn't strictly true, but generally ionic compounds are not highly soluble in organic solvents because ionic compounds need a highly polar solvent to dissolve well (such as water) and in general organic compounds are not as polar as water. Remember, like dissolves like. However, many ionic compounds are very soluble in a variety of organic solvents, just not as much as in water.
For example, ionic compounds: inorganic acids, salts, bases; many organic compounds, etc.
Solvents dissolve ionic compounds by surrounding and separating the ions through the process of hydration, where solvent molecules interact with the ions and weaken the attraction between them. This allows the ions to move freely in the solution, breaking the ionic bond in the solid lattice and dispersing throughout the solvent.
For example, ionic compounds: inorganic acids, salts, bases; many organic compounds, etc.
PbCl2 is not soluble in organic solvents because it is a polar compound and organic solvents are nonpolar. Organic solvents are generally unable to dissolve ionic compounds like PbCl2 due to the difference in polarity between the solute and solvent.
Ionic compounds are insoluble in organic solvents because organic solvents do not provide the necessary interactions for ionic bonding to be broken and replaced by interactions with the solvent molecules. Organic solvents lack the ability to stabilize the charged ions in the ionic compound, leading to poor solubility.
Water is a good solvent because it has polar -O-H groups and the same reason makes water a good solvent for polar compounds as acetic acid and hydrochloric acid. Water is not a good solvent for non polar compounds such as bromine and iodine.
Ionic compounds do not dissolve in non-polar compounds. They can dissolve only in polar compounds. Dissolution is actually dissociation of the ionic compounds and the polar solvent into constituent ions and development of weak forces of attraction called hydrogen bonds. The dissociation is not necessarily complete always.
The saturation of butanol with sodium chloride is to avoid further ionic or inorganic compound to dissolve, now only non polar or organic compounds may dissolve in butanol during extraction.
