Surfactant is used in the lungs to break water tension within the alveoli. Without it, the alveoli will collapse and you will suffocate and die.

The lipophilic tail of a surfactant molecule is considered to be?
The lipophilic tail of a surfactant molecule is considered to be hydrophobic, meaning it repels water and is attracted to nonpolar substances such as oil or grease. This allows the surfactant to interact with both water and oil, helping to emulsify them and form stable mixtures.
Why does oil miscible in solution of surf and water?
Oil is miscible in a solution of surfactant and water due to the amphiphilic nature of surfactants. Surfactants have both hydrophobic (oil-attracting) and hydrophilic (water-attracting) parts, which allow them to interact with both oil and water molecules, facilitating the formation of stable emulsions. This enables the oil to disperse evenly in the water, making it miscible.
What describes the role of surfactant in the respiratory system?
Surfactant helps reduce surface tension within the alveoli, thus preventing each alveolus from callapsing as air moves in and out during respiration.
What is the head of a surfactant molecule?
The head of a surfactant molecule is typically hydrophilic, meaning it is attracted to water. This hydrophilic head allows surfactants to dissolve in water and interact with other molecules.
Is a surfactant a heterogeneous mixture?
No, a surfactant is a type of molecule that can lower the surface tension between two substances and is typically a homogeneous mixture when dissolved in water.
What are solid shampoos?
Basically it is detergent (surfactant/soap) but without water or with very little water.
Suspensions can be wetted before adding water by using a wetting agent or a?
surfactant
How is the solubility of Tween 20 in water?
Tween 20 is a surfactant that is soluble in water. It is a nonionic surfactant composed of a hydrophilic polyethylene glycol chain and a lipophilic sorbitan monolaurate chain, making it soluble in both water and oil.
What do surfactant do?
A surface-active agent 'surfactant' usually cleans something. ie -soap is a surfactant.
What is the role of Zimbabwean government in industrial relations?

Can you emulsifier instead of surfactant?
Emulsifiers are a type of surfactant that stabilizes emulsions by reducing the surface tension between oil and water. So yes, emulsifiers can be used as surfactants in formulations that require emulsion stability.
What is the interfacial properties of surfactant solution?
Surfactant molecules have dual properties as they contain both hydrophilic (water-attracting) and hydrophobic (water-repelling) regions. This allows them to localize at the interface between two immiscible phases, such as oil and water, reducing surface tension and facilitating emulsification. Surfactants can also form micelles in solution, where the hydrophobic tails are shielded from the surrounding solvent by the hydrophilic heads.
