Smelling salts release ammonia (NH3) gas, which triggers an inhalation reflex (that is, causes the muscles that control breathing to work faster) by irritating the mucous membranes of the nose and lungs. Although these hypothetical mechanisms have been discussed, it is likely that smelling salts are not effective.
The salt end of the soap molecule is ionic and hydrophilic (water soluble). When grease or oil (non-polar hydrocarbons) are mixed with a soap-water solution, the soap molecules work as a bridge between polar water molecules and non-polar oil molecules.Since soap molecules have both properties of non-polar and polar molecules the soap can act as an emulsifier.he salt end of the soap molecule is ionic and hydrophilic (water soluble).
