Water is not apolar; it is a polar molecule. This polarity arises from the uneven distribution of electron density, which leads to a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. This polarity allows water to form hydrogen bonds, giving it unique properties such as high surface tension and solvent capabilities. In contrast, apolar molecules do not have charged regions and do not interact well with polar substances like water.
What else can I help you with?
Why should water not be described as a universal solvent?
because there are 2 totally different types of molecules, you have the polar and apolar molecules. the polar molecules will only dissolve in a polar solvent, the apolar moleculesin a apolar solvent. this is the reason why oil doesn't mix with water. oil is apolar and water polar
Why can steroids easily cross the membrane but not glucose and water molcues?
Most steroids are apolar whereas water and glucose are not.
Does adipose tissue have more H2O than other tissue?
Doubtful, adipose tissue store apolar lipids, which don't mix with polar water molecules.
Why the gas is above the oil and the oil is above the water?
This is because gas is less dense than oil, and oil is less dense than water. In a liquid mixture, the substances will separate based on their densities, with the least dense substance rising to the top. This results in the gas being above the oil, and the oil being above the water.
What is apolar solvent?
An apolar solvent is a solvent that lacks a significant separation of charge within its structure, resulting in a lack of significant electrostatic interactions with solute molecules or ions. Apolar solvents are typically nonpolar compounds like hydrocarbons, which are unable to form hydrogen bonds or dipole-dipole interactions with solutes that have polar groups. Examples include hexane, benzene, and carbon tetrachloride.

What is carbon dioxide dessolved in?
It's apolar, so it would more easily dissolve in apolar substances, though it can be dissolved in water easily enough if the temperature is low. Such is the case with soft drinks.

Most steroids are apolar whereas water and glucose are not.
Does adipose tissue have more H2O than other tissue?
Doubtful, adipose tissue store apolar lipids, which don't mix with polar water molecules.
What is oil in physical science?
In physical science, oil is a liquid and mostly denser with respect to water. Most oils are apolar by nature, which means they are hydrophobic too.
Why the gas is above the oil and the oil is above the water?

What makes a cell membranes waterproof?
While water does pass through the membrane if it has enough momentum, the apolar part of the lipid bilayer generally is what makes the membrane more or less waterproof.
Why is the leuco base of indigo water soluble?
Water can dissolve polar compounds but not apolar. By this way the formation of leuco base of indigo give a polar compound wich can be dissolve in water. This leuco base is a sodium salt, and consequently it is polar. Because I'm french my English is no perfect, so please don't insult me.
Is water a univeral solvent?
No. There is no "universal solvent". That said, water is a pretty darn good solvent for a wide variety of materials.Added:Water is a very good solvent for polar compounds (eg. sugar) and ionic compounds (eg. salt) but not for 'apolar' (hydrophobic, means does not LIKE water) substances like fat, grease, oil, gasoline etc.
How can you disolve vasaline?
Petroleum is a hydrocarbon, and apolar. Probably made off very large molecules of this type. By putting it in a mixture which contains similar looking molecules, which would be able to bond via Van der Waals weak forces. Since it's apolar and doesn't have ends which can bond via hydrogen bonds, vaseline is definitely more hydrophobic than hydrophilic, so it doesn't wash off with water. If you find a molecule that has both a hydrophobic (to bond with the vaseline molecules) and hydrophilic, it's the ideal type to dissolve vaseline and wash it off. If the idea is not to wash it off but make a solution, then a big apolar molecule which can make plenty of Van der Waals connections with the vaseline molecule (the more the better) can work.
Why apolar bear living in dessert?
Most polar bears spend time out on the frozen Arctic ice flows hunting seals. The Arctic a dessert.
