Polar solvents are characterized by regions with strong positive or negative electrical charges. For example water, the most usual polar solvent, is negatively charged on the oxygen end of the molecule and positively charged on the hydrogen end, simply because the oxygen nucleus attracts the shared electrons more strongly than the hydrogen nuclei do (and the hydrogen atoms are arranged at the points of a tetrahedron, rather than in a straight line with the oxygen atoms). And a typical polar solute such as sodium chloride, has positively charged sodium ions and negatively charged chlorine ions because chlorine has a much stonger attraction for electrons than sodium does, so it takes an electron from sodium. And then, given Coulomb's Law, we get an attraction between oppositely charged chemicals or portions of chemicals; the positively charged sodium ions would be attracted to the negatively charged oxygen region of the water molecule, the negatively charged chlorine ions are attracted to the positively charged hydrogen region of the water molecule. It is these electrostatic attractions which cause the solute to dissolve in the solvent.

What properties does water have as a result of being a Polar molecule?
Water being polar have the ability to dissolve other polar compounds(like dissolves like).Most polar compounds dissolve only in water. Since water is a polar compound,its H atom forms weak hydrogen bonds with other more electronegative atoms and this is the cause of dissolution of many compounds in water.
Nonpolar solvents will most easily dissolve solids that are?
Nonpolar solvents will most easily dissolve solids that are also nonpolar or have weak polar interactions. This is because like dissolves like, meaning substances with similar polarities are more likely to mix together. Examples of nonpolar solids that dissolve well in nonpolar solvents are hydrocarbons like fats, oils, and grease.
What are properties of hydrophobic and hydrophilic?
Hydrophobic substances repel water and do not mix well with it due to their non-polar nature, while hydrophilic substances attract and bond with water molecules due to their polar nature. Hydrophobic substances tend to be nonpolar and often include oils and fats, while hydrophilic substances tend to be polar and include salts and sugars.
Does non polar mean hydrophobic or hydrophilic?
Non-polar molecules do not dissolve in water as they cannot form hydrogen bonds, and so they are hydrophobic.A non-polar molecule is one that the electrons are distributed more symmetrically. They do not have an abundance of charges at the opposite sides, and the charges cancel out each other.
Is the molecule polar and hydrophilic or hydrophobic?
The polarity of a molecule determines whether it is hydrophilic (attracted to water) or hydrophobic (repelled by water). If a molecule is polar, it is typically hydrophilic, meaning it can dissolve in water. If a molecule is nonpolar, it is usually hydrophobic and does not mix well with water.
Do polar substances dissolve in non-polar liquids?
No, polar substances do not dissolve well in non-polar liquids because they have different intermolecular forces. Polar substances are attracted to other polar substances due to their opposite charges, while non-polar substances are attracted to each other due to London dispersion forces.
Do polar subtances dissolve well in water?
Yes, polar substances dissolve well in water because water is a polar molecule with positive and negative ends that can interact with other polar molecules through electrostatic interactions. This allows substances with polar characteristics to easily dissolve in water.
Are polar and non polar liquids soluble?
Generally not. The general rule to go by is like dissolves like. Polar substance will dissolve other polar substances while nonpolar substances will dissolve other nonpolar substances.
Will salt and sugar dissolve in petrol?
Unlike salt and sugar, petrol is a nonpolar substance, meaning that the electrons in its molecules are evenly distributed, rather than concentrated in some areas to make the molecule negatively charged on one side and positively charged on the other, as is the case with polar substances. Polar substances, as well as ionic substances such as salt, tend to dissolve more effectively in other polar substances, such as water, while nonpolar substances tend to dissolve well in nonpolar substances, such as oil. So while salt and sugar dissolve well in water, and oil might dissolve well in petrol, salt and sugar will not dissolve to any great degree in petrol.
Explain the statement like dissolves like?
Oh, dude, it's like this: "like dissolves like" is just a fancy way of saying that polar substances mix well with other polar substances, and nonpolar substances mix well with other nonpolar substances. It's basically like how introverts hang out with introverts and extroverts hang out with extroverts. So, if you want your substances to get along and mix nicely, just remember: like attracts like!
Does polar or non polar dissolve in water?
Polar substances dissolve in water because they have similar polar characteristics that allow them to interact and mix well. Non-polar substances, on the other hand, do not dissolve in water because water is a polar molecule and cannot effectively interact with non-polar molecules.
Why does cyclohexanone dissolve in benzophenone and not in water?
Cyclohexanone and benzophenone are both non-polar. Water is polar. "Like dissolves like" so non-polar substances dissovle other non-polar substances and polar substances dissolve other polar substances.
Substances unable to dissolve in water?
Substances that are unable to dissolve in water are considered hydrophobic. This includes substances such as oil, fats, and waxes. These substances are non-polar and do not interact well with the polar water molecules, leading to limited or no solubility.
What is the ability to dissolve other chemicals?
Solubility is defined as the ability of one substance to dissolve into another substance. Polarity is the main property that governs solubility. Polar molecules will dissolve in polar solvents and non polar molecules will dissolve in non polar colvents. Just remember like dissolves like. Water is polar and it is known as the univeral solvent.
Is benzene soluble in fat?
Benzene is not soluble in fat; it is a non-polar solvent and does not mix well with polar substances like fats, which are composed of long-chain fatty acids that have polar characteristics. Instead, benzene is more soluble in other non-polar solvents. This lack of solubility is consistent with the principle that "like dissolves like," meaning polar substances tend to dissolve in polar solvents, while non-polar substances dissolve in non-polar solvents.
What kinds of substances dissolve water?
Powders like sugar, salt, baking soda, etc.
What kinds of substances dissolve in water hydrophilic nonpolar hydrophobic oily?
Hydrophilic substances, which are polar or ionic, tend to dissolve well in water due to their ability to form hydrogen bonds or interact with water molecules. In contrast, nonpolar or hydrophobic substances, such as oils, do not dissolve in water because they lack the necessary interactions with water molecules. This difference in solubility is primarily due to the polar nature of water, which favors interactions with other polar or ionic substances.
