Why are some substances not able to be dissolved in water?
Some substances are not able to dissolve in water because they do not have polar molecules that can interact with the water molecules. Nonpolar substances, like oil, do not mix with water because water is a polar molecule and can only dissolve other polar or ionic substances. Additionally, the intermolecular forces between the solute and solvent may not be strong enough to overcome the forces holding the solute together.
What substances that do not dissolve easily in water?
you know water is a polar substance and can solve only polar substances and ionic substance it is not able to solve fat , oil or other organic (usually) substances (oil). by ionic substance I meant substances such as salt
Why cant water dissolve compounds such as oil?
Water is a polar molecule, while oil is a nonpolar molecule. Polar molecules like water are only able to dissolve other polar or ionic substances, not nonpolar substances like oil. This is due to the differences in their electrostatic interactions, preventing water from effectively breaking down and dissolving oil molecules.
How is water able to dissolve ionic substances?
Water is able to dissolve ionic substances because of its polar nature. The water molecule has a positive and negative end, allowing it to attract and surround the charged ions in the ionic substance, breaking them apart and dispersing them throughout the water. This process is called hydration and helps to dissolve the ionic substance in water.
What would dissolve best in oil?
Substances that are nonpolar or nonpolar complexes, such as lipids, certain flavors, and some drugs, dissolve best in oil. Examples include essential oils, vitamin A, and vitamin E. Oil is not able to dissolve polar substances like water-soluble vitamins or salts.

What is meant by like in the solubility guideline like dissolves like?
There are basically two types of solvents, polar and non-polar. This refers to the electrical charges in a molecule; polar molecules have positive and negative poles, non-polar molecules don't. The most familiar polar solvent is water, familiar non-polar solvents would be such things as gasoline, cooking oil, etc. So, polar substances dissolve in polar solvents, and non-polar substances dissolve in non-polar solvents. A polar substance will not dissolve in a non-polar solvent. Soap is a chemical that has both polar and non-polar elements to its molecular composition, and therefore is able to bridge the gap between polar and non-polar.
Why do so many substances dissolve in water?
The difference in the electronegativity of oxygen and water pulls the bonded electrons closer to the oxygen atom than the two hydrogen atoms. This creates a dipole moment (a charge separation along the bond), leaving the oxygen with a partial negative charge, and the hydrogen with a partial positive charge. This is known as a "polar" molecule", and will dissolve other polar substances. With the exception of homo-nuclear diatomics (N2, O2, etc.) all molecules contain at least some degree of polarity, and therefore are able to dissolve in a polar substance. Because water is very polar, it tends to dissolve other highly polar substances ("like dissolves like") extremely well, and will even dissolve molecules that are considered "non-polar" (but they still have a small dipole moment), albeit to a lesser extent.
Why are two nonpolar substances able to dissolve in each other?
Two non-polar substances share similar attractive forces in their molecules, which is what enables them to dissolve in each other. The dissolving medium in a solution is referred to as a solvent.

Water is able to dissolve ionic substances because of its polar nature. The water molecule has a positive and negative end, allowing it to attract and surround the charged ions in the ionic substance, breaking them apart and dispersing them throughout the water. This process is called hydration and helps to dissolve the ionic substance in water.
Are non polar molecules soluble in water?
No.Water can't dissolve non-polar molecules. Water is a polar molecule. Since polar molecules can only dissolve with polar molecules, and non-polar molecules can only dissolve with non-polar molecules, water and non-polar molecules don't react together. Exception:- Some very small non-polar molecules can dissolve in water, like oxygen (O2)
What would dissolve best in oil?
Substances that are nonpolar or nonpolar complexes, such as lipids, certain flavors, and some drugs, dissolve best in oil. Examples include essential oils, vitamin A, and vitamin E. Oil is not able to dissolve polar substances like water-soluble vitamins or salts.
Is food coloring polar?
Yes, food coloring is typically polar because it is made up of molecules that have polar bonds. This allows food coloring to easily mix with other polar substances and water, resulting in uniform coloring effects in food and beverages.
Is starch is soluble in chloroform?
No, starch is not soluble in chloroform. Starch is a polar molecule, while chloroform is non-polar, so they are not able to dissolve in each other.
Why isn't water always a solvent?
Water isn't always a solvent because not all substances can dissolve in water. Water can dissolve many substances due to its polarity and ability to form hydrogen bonds, but substances that are non-polar or have larger molecules may not be able to dissolve in water.
