Answer 2

Micelles Formation Cleans Clothes

Explanation:

(a) Soap is the sodium salt (or potassium salt) of a long chain carboxylic acid (fatty acid) which has cleansing properties in water. Example: Sodium stearate, C_1_7H_3_5COO-Na^+

(b) A soap molecule has two parts: the long-chain organic part and the ionic part containing the -COO- Na+ group. It has to be remembered that this is not an ion, the atoms are all covalently bonded, the electrical charges show how the charges get polarized in the group.

• A soap molecule structure is shown in the figure attached.

(c) The cleaning action of soap is shown with figure attached.

Soaps have two ends, one called Hydrophilic (Water dissolved) and other Hydrophobic (Dissolves in Hydrocarbons)

• At the point when the cleanser is at the outside of water, the hydrophobic 'tail' of cleanser won't be dissolvable in water and the cleanser will adjust along the outside of water with the ionic end in water and the hydrocarbon 'tail' distending out of water. Inside water, these atoms have a one of a kind direction that keeps the hydrocarbon parcel inside the water.
• This arrangement is known as a micelle. At the point when a grimy fabric is placed in water containing broke up cleanser, at that point cleanser as a micelle can clean. The hydrocarbon parts of the bargains join to the sleek soil particles and entangle them at the focal point of the micelle. the ionic finishes in the micelles stay connected to water
• When a dirty cloth is put in water containing dissolved soap, then soap in the form of a micelle is able to clean. The hydrocarbon ends of the soap attach to the oily dirt particles and entrap them at the center of the micelle. Oily particles gets attached with
• The ionic end remains attached with water. On agitating the wet and bad clothes in n solution of soap, the cloths will be getting cleaned, as the soap micelles get stick to the oily and dirt particles.
