Acetone is a Good SolventThis explains why it's used for different purposes. '' In the case of acetone, it's slightly more polar than water. Water is also a polar solvent.
Water, for example, will dissolve salt or sugar. Some solvents, alcohol and acetone for example, are “miscible” with water meaning that they can be mixed with water in various proportions to create mixtures which may exhibit the solvent properties of both liquids.
Many kinds of plastic do not dissolve in acetone. Polypropylene and nylon are unaffected, PTFE unsurprisingly handles it just fine as well. Two kinds of plastic that do dissolve in acetone are PVC and polystyrene.
Acetone is a polar molecule that also has asymmetrical nonpolar covalent bonds between its carbon atoms which do not affect is polarity.
Acetone is a polar molecule because it has a polar bond, and the molecular structure does not cause the dipole to be canceled.

It is true that acetone is less polar than ethanol. I thought the dipole moment is proportional to polarity, and if so, the dipole moment of acetone should be lower than ethanol. But the dipole moment of acetone is higher than ethanol.
Since acetone is molecular, the intramolecular forces (forces within the molecule) between atoms that holds the molecule are covalent bonds. Covalent bonds are bonds between two non metal atoms. Single covalent bonds are found between the hydrogens and the carbons, as well as between the carbons.
Acetone is an excellent solvent because it can dissolve other substances. Given that it is miscible and polar, it can work with products ranging from water to different organic compounds. Because of this polarity, acetone can mingle with polar solvents like water.
Acetone is capable of dissolving many fats and resins as well as cellulose ethers, cellulose acetate, nitrocellulose, and other cellulose esters. Because of the latter quality, acetone is used extensively in the manufacture of artificial fibres (such as some rayons) and explosives.
Acetone is a common solvent and does evaporate completely. If you spill acetone at home it doesn't leave an obvious stain because it's colorless and evaporates quickly.
sure you can dilute it with water if you want to however diluting it will make it work slower which means you leave acetone on the nail longer which means it could melt it more easily.
Acetone is a powerful organic solvent that can be used to easily and quickly remove ink from paper. It works on most types of ink, regardless of the constituents, and is cheaply and readily available. It will remove most ink without causing any damage to the paper.
Acetone and pure water are soluble in all proportions; they are completely miscible. Obviously, acetone and salt water are incompatible and therefore immiscible; they do not mix in all proportions. The dye methyl violet, which dissolves better in acetone than in water, accumulates in the acetone layer.
What temperature does acetone boil at?
Acetone dissolves completely when mixed with water.In this reaction, acetone is the solute and water is the solvent. When acetone mixes with water, hydrogen bonds form between these compounds. These bonds will keep acetone dissolved completely in water, resulting in a homogeneous solution.
Acetone isn't a sterilising agent either. It is generally ineffective against spore-bearing bacteria and fungi even in prolonged exposure (i.e. 20+ minutes). Inability to kill spores cannot qualify the agent to be called a steriliser for critical-use items.
Water is a Polar Covalent MoleculeThe unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
Depending on the solubility of a solute, there are three possible results: 1) if the solution has less solute than the maximum amount that it is able to dissolve (its solubility), it is a dilute solution; 2) if the amount of solute is exactly the same amount as its solubility, it is saturated; 3) if there is more
The molecular formula for benzene is C6H6. Benzene is a non-polar molecule. Benzene is a symmetric planar ring of 6 bound carbon atoms with each carbon terminated by hydrogen to satisfy valency — as a result there is an even 'pull' of electrons in all 6 directions (between C-H in the bonds), thus benzene is nonpolar.
Generally, if all three of the intermolecular forces of attraction are roughly equal, the substances will be soluble in each other. This means that ionic or polar solutes dissolve in polar solvents, while non-polar solutes dissolve in non-polar solvents.
For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
2: As potassium chloride (KCl) dissolves in water, the ions are hydrated. The polar water molecules are attracted by the charges on the K+ and Cl− ions.
Simply mix the liquid with an equal part of water and allow the mixture to sit undisturbed. Examine the mixture after the liquids have sat together for a time. If they have not separated, but have formed a solution, the unknown liquid is polar. If there is a clear boundary between the two liquids, it is non-polar.
CCl4 that is carbon tetrachloride is nonpolar because all the four bonds are symmetrical, and they are they extended in all the directions.
Rubbing alcohol molecules have a polar and nonpolar part, which means they are able to form hydrogen bonds with water and therefore able to mix with it. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent.

The solubility of lower alcohols is due to the existence of hydrogen bonds between water and polar -OH group of alcohol molecules. The -OH group in alcohols and phenols contain a hydrogen bonded to an electronegative oxygen atom. Thus they form hydrogen bonds with water molecules.
Due to less extensive hydrogen BONDING, liquid NH3 is a better solvent for organic compounds which are more soluble than in water. Due to its lower viscosity, liquid NH3 provides a better medium for the movement of ions in it.
Chloroethane is unable to form hydrogen bonds with water. Hence, it is insoluble in water.
A good example of this is ethanol which will dissolve in both water (a polar solvent) and gasoline (a non-polar solvent).
Answer. Explanation: Sugar because faster to dissolve in water while flour is the insoluble one.
When the lattice energy is larger than the energy released by solvation of the ions, namely that of Na+ by complexation with acetone, the compound becomes insoluble and precipitates from the solution (source).
Benzoic acid or benzene-carbonic-acid is a monobasic aromatic acid, moderately strong, white crystalline powder, very soluble in alcohol, ether, and benzene, but poorly soluble in water (0.3 g of benzoic acid in 100 g of water at 20 °C).
