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.

Soap is not necessary for removing salt from your hands. Salt is very easy to clean off your hands with just water.
Boiling off the water from a salt solution will separate the solid salt and water (which can be collected by a condenser).
well, add table salt to soapy water (trust me it works, i did a science fair project on this) and leave the salt/soap/water mixture for 6-8 hours or overnightand filter.add. This is actually a serious problem as dairy cows get a condition commonly known as 'bloat' caused by excess foaming of stomach contents. Various remedies have been made to relieve this condition.
Hold a magnet over it and the iron will fly out of the salt and stick to it, and the salt will stay there.
<p>You can separate the sand by filtration, but still the salt (mainly sodium chloride) is dissolved in the water. Then, you can separate the salt from water by distillation. The liquid you collect after water vapor is chilled is distilled water. You can use other methods to separate sand as sedimentation (usually slower than filtration) and salt as reverse osmosis.<p>
Salting out is used in the preparation of soap to help separate the soap from the glycerin during the saponification reaction. By adding salt to the soap mixture, the soap molecules are forced to come out of solution, making it easier to separate them from the glycerin layer.
The salt reacts with the water that would go toward acting as a solvent for the organic molecule. The inorganic salt is more "thirsty" than the organic molecule and deprives the soap of sufficient water to keep it soluble. This causes the soap to precipitate.
1. Sodium chloride help to separate soap from the mixture by precipitation. 2. Adding sodium chloride the soap is more hard.
dnt no you can separate glycerin to add brine solution at the time of soap trace brine solution is a salt water and salt is insoluble in glycerin so after pouring salt water the soap separated in two phases soap upper phase and the spent soap lye(lower phase)the spent lye soap was filter to remove unwanted soap particles after hydrochloric acid treatment and then neutralizing with sodium hydroxide solution and then keep in oven for drying this stage there will be two layers salt and glycerin layer care fully decanted and store in a refrigerator
Alcohol can dissolve soap but not salt. When alcohol is applied to soap, it can break down the soap molecules and cause it to dissolve. Salt, on the other hand, does not dissolve in alcohol due to differences in their chemical structures.
Either baking soda or soap is salt.
When a salt solution is added to the saponification mixture, the presence of excess ions from the salt solution can disrupt the balance within the mixture. This disruption can lead to the formation of insoluble salts, which precipitate out of the solution. The precipitation of the salt helps separate it from the soap and other components of the mixture.
Salt is added to soap solution to help precipitation and separation of salt.
For solubility of soap
Salt, is used to flavor and preserve food. Soap is used to clean and disinfect
Salt is needed in soap making to harden it as it solidify's so that it does not become mushy
No, it cannot separate salt from a salt solution. This is because salt is soluble in water.
