They are those that are ionized in solution and were the hydrophobic group is negatively charged They are constituted by a linear alkyl chain. For example: sulphonic acid.
It's a chemical reaction that occurs between an acid and a base producing a salt and water.
It's an element that acts as a detergent, emulsifier or humectant and that allows to reduce the surperficial tension that exists in a fluid. In general, these are substances that influence the contact area created between two phases.
The superficial tension refers to the level of energy that is needed for a liquid to increase its surface area per unit area. This means that there is a resistance in the liquid to increase the surface.
Surfactants are composed of hydrophobic parts which reject water and hydrophilic parts which are soluble in water. So when the surfactant is linked to water, the molecules of the first group remain at the surface level while the hydrophilic molecules are submerged causing bubbles bubbles to form.
