The best way to tell if something will dissolve is to look at the polarities of the solvent and the solute. If the polarities of the solvent and solute match (both are polar or both are nonpolar), then the solute will probably dissolve.

When one substance dissolves into another, a solution is formed. A solution is a homogeneous mixture consisting of a solute dissolved into a solvent . The solute is the substance that is being dissolved, while the solvent is the dissolving medium.

When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution. If a solid dissolves on mixing its particles break apart and form a loose association with the liquid (solvent) particles.

Solid LiCl dissolves in water because: A. The Li+ ions are attracted to the oxygen atom () of water. The Cl– ions are attracted to the oxygen atom () of water.

Polar solvents dissolve polar or charged materials easily, for example salt and sugar. Oil is non-polar. Non-polar molecules dissolve more easily in non-polar solvents. Baby oil will completely dissolve in cooking oil.

Sugar dissolves easily in water and oil does not. Water has a low solubility when it comes to oil. Since oil is not soluble in water, it will never truly dissolve.

Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water’s hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.

So what happens when you try to mix oil and water? The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water.

If you shake the oil and water together then the oil breaks up into tiny droplets and becomes distributed in the water forming a mixture. By vigorously mixing the emulsifier with the water and fat/oil, a stable emulsion can be made.

Lecithin is a phospholipid molecule found in soy and isolated in refining of soy oil. It is an effective and popular food emulsifier. Egg yolk contains two emulsifiers—lecithin, which promotes oil in water emulsions, and cholesterol, which promotes water in oil emulsions.

When it comes to making an emulsification, the key is to add the oil slowly into the mixture with the vinegar and emulsifier. Too fast and the oil and vinegar will want to stay separated. Also pay attention to the temperature of your emulsifier to ensure it’s not too hot or too cold compared to the oil and vinegar.

The suggested use is 2 drops of emulsifier with 2 drops of essential oil and 1 ounce of water. EOE is in a concentrate form. What is emulsion? Emulsion is enabling the mixture of two liquids that do not normally mix.

Essential oils are highly concentrated, volatile substances. In order to be used safely, they should be diluted in another safe substance, like water, a skin care oil or an unscented lotion or liquid soap.

Emulsifiers and stabilisers are both classified as additives. While emulsifiers help to mix together substances which do not easily mix, such as oil and water, stabilisers on the other hand, ‘stabilise’ the desired consistency and stops these substances from separating again after they have been mixed.
