Can soap be dissolved in water?
Oil is insoluble in water (insoluble means it does not dissolve).
How does soap work with water to remove oily dirt?
Soap contains particles that have a polar end and a non-polar end. These particles are able to attach to oil particles and to water particles, enabling the oil to dissociate in the water and disperse. In this way, soap acts as an emulsifying agent.
What is the structure of a representative soap molecule?
A soap molecule typically consists of a long hydrophobic tail, composed of a carbon chain, and a hydrophilic head, which contains a charged group such as sulfate or carboxylate. When dissolved in water, soap molecules align themselves with the hydrophobic tails pointing inward and the hydrophilic heads outward, forming micelles that can trap dirt and oil to be washed away.
Why is soap able to clean the oil and dirt off your bodies?
Soap molecules have a dual nature - one end is attracted to water (hydrophilic) and the other end is attracted to oil and dirt (hydrophobic). When you mix soap with water and rub it on your skin, the hydrophobic end attaches to the oil and dirt, while the hydrophilic end allows them to be rinsed away with water, effectively removing them from your skin.
Why is soap used to remove grrase?
Soap is capable of breaking down and removing grease because its molecules have two distinct ends - one end attracts water molecules while the other end attracts oil and grease molecules. When soap is mixed with water and applied to grease, the oil-grabbing end attaches to the grease, allowing it to be rinsed away with water.
How can you make salt dissolvable in oil?
Salt will dissolve in oil very slightly but not truly. salt is an ionic compound (it has a positive/negative side) and oil is usually covalent (there is no charge). The rule for solubility of compounds is that like dissolves like, so ionic dissolves ionic and covalent dissolves covalent.
Why does the tail end of the detergent molecule dissolves in oil while the head dissolves in water?

Does petrol dissolve oil?
Water is a polar molecule, and therefore dissolves other polar substances and many ionic compounds because of its partially positive hydrogen end and its partially negative oxygen end. However, petrol is a nonpolar substance and only dissolves other nonpolar substances.
How do separate soap from salt?
Soap acts as an emulsifying agent. An emulsifier is capable of dispersing one liquid into another immiscible liquid. Nearly all compounds fall into one of two categories: hydrophilic and hydrophobic. Water and anything that will mix with water are hydrophilic. Oil and anything that will mix with oil are hydrophobic. When water and oil are mixed they separate, which is why hydrophilic and hydrophobic compounds just do not mix. When grease or oil is mixed with a soap- water solution, the soap molecules work as a bridge between polar water molecules and non-polar oil molecules. It doesn't separate them -- in fact, it does the opposite. Soap allows water and oil to mix.See the Related Questions to the left for more information about how soap works.

Why does soap join oil and water?
Soap is a combination of a non-polar hydrocarbon chain (tail), and a very polar head. The non-polar tail (no free electrons, balanced bonds) section of the soap interacts with the oil. The polar head (free pairs of electrons in the chemical bonds, ionic or unbalanced bonds) dissolves in the water. Many descriptions indicate that the soap forms micelles around the oil with the non-polar tails pointing inward interacting with the oil, and the polar heads outwards interacting with the water... thus insulating the oil from the water. Since this was in science experiments, it would be an interesting project to make a batch of lye soap using cooking oil, lard, or shortening, and lye (sodium hydroxide) and water. Instructions are on the WWW. LYE is dangerous and must be handled with caution and with parental guidance.

Why ionic compounds are insoluble in non-aqeous solvents like petrol or kerosine oil?
non aqeous solvents like petrol and kerosine are having long carbon chains and both the end r having non polar groups generally. so there is no separation of charges in them to incorporate the ionic compounds in them........ answer 2...like dissolves like... ;)
Does salt contain oil?
Table Salt is Sodium Chloride (NaCl), an ionic compound. It does not contain oil, nor does it dissolve well in oil. However, "salt" is a generic term which describes an ionic bonded compound with an electro-positive part such as Sodium (Na+) and an electronegative part (Cl-). Many natural oils such as vegetable oil or lard have an carboxylic acid as part of it. One can make soap by mixing a natural oil with water and sodium hydroxide (Lye) or Potassium Hydroxide (Potash). This creates a "salt" with the oil which dissolves in water, and is able to capture oils. So... natural soaps are salts that contain oils.
Why is soap a compound?
Soap is a compound because it is made up of two or more elements chemically bonded together. It typically consists of molecules containing a hydrophobic tail and a hydrophilic head, which allows it to interact with both water and oil molecules to effectively clean surfaces.
