Soap molecule consist of two parts, one hydrophillic and other one is hydrophobic Hydrophobic part of soap is dissolved with dirt molecule and hydrophillic remains suspended in water. Thus more molecules of soap are attached to dirt having their one end suspended in water to form a micelle. Since ethanol is not as polar as soap micelle will not be formed in other solvents such as ethanol.

How a micelle allows grease or oil to dissolve in water?
Micelles are formed by surfactant molecules in water. The hydrophobic tails of surfactant molecules attract grease or oil molecules, while the hydrophilic heads interact with water. This structure encapsulates the grease/oil molecules within the micelle, allowing them to be suspended in water and washed away.
How does formation take place?
water condensates and makes clouds in the sky.when their full of water it rains
What is the name of the structure formed when a soap coats an oily particle to make it water soluble?
The structure is called a micelle. It forms when soap molecules surround oily particles, with the hydrophobic tails of the soap facing inward and the hydrophilic heads facing outward, allowing the oily particle to be dispersed in water.
What happens to flour when water is added?
When water is added to flour, it hydrates the protein gluten and starch molecules in the flour, causing them to swell and absorb moisture. This process activates the gluten, resulting in the formation of a cohesive dough. This dough can then be kneaded and shaped to create various baked goods.
What happens when water is added to the gas jars in which sulphur was burnt?
When water is added to the gas jars in which sulphur was burnt, a chemical reaction occurs. The sulphur dioxide gas produced from burning sulphur reacts with the water to form sulphurous acid (H2SO3). This reaction results in the formation of a colorless solution with acidic properties.

What bases form when an acid is added in water?
When an acid is added to water, base ions are formed through the transfer of protons (H+) from the acid to water molecules. This results in the formation of hydroxide ions (OH-) in the water solution.

How does pospholipids behave in water?
Considering that phospholipids are amphiphilic molecules, such as soaps and detergents, form "micelles" (globular aggregates whose hydrocarbon groups are out of contact with water). This molecular arrangements eliminates unfavorable contacts between water and hydrophobic tails (the fatty acids) of the phospholipids and yet permits the solvation of the polar head groups (the phosphate group).Now, we have to consider that micelle formation is a cooperative formation, that is, an assembly of just a few amphiphiles cannot shield its tails form contact with water. Consequently, dilute aqueous solutions of amphiphiles do not form micelles until their concentrations surpasses a certain critical micelle concentration (cmc). According to this, above the cmc, almost all added amphiphiles aggregates to form micelles. The value of the cmc depends on the identity of the amphiphile and the solution conditions, for example, biollogical lipids, most of which have two large hydrophobic tails (the fatty acids), the cmc values are generally < 10-6 M.
Why micelle not form in ethanol?
It was found that methanol and ethanol destabilize the formation of both micelles and the protein detergent complex. {destabilize = can be moved easily} no way - micelles form by the hydrophobic character of lipid tails but ethanol is not water and even though there is some polarity at the hydroxyl group it wouldn't be free enough (unobstructed) to push the fatty acids together - the ethanol chain would probably intermingle with the lipid chairs too
What is a bicelle?
A bicelle is a self-assembled aggregate of phospholipid in water, which combines flat bilayer-like and curved micelle-like features.
What happens when Hcl is added to sodium thiosulphate?
When HCl is added to sodium thiosulfate, a redox reaction takes place, resulting in the formation of solid sulfur (S) and sodium chloride (NaCl) in solution. Additionally, the reaction produces sulfur dioxide gas (SO2) and water (H2O) as byproducts.
Why do amphipathic molecules form micelles in water?
Amphipathic molecules are by definition those that contain both hydrophobic (water hating) and hydrophilic (water loving) regions. The area of the molecule that likes water tends to stay in the aqueous region whereas the region of the molecules that hates water tends to cluster with other hydrophobic regions. This untimately results in the hydrophobic regions packing together and forming a region that is impervious to water molecules. Such a structure is called a micelle
When do snowstorms take place?
When there is a large concentration of water in cloud formation, when the air temperature is below freezing.
What happens when an acid is added to a base?
When an acid is added to a base, a neutralization reaction occurs, resulting in the formation of water and a salt. The acid donates a proton (H+) to the base to form water. The remaining ions from the acid and base combine to form a salt.
