Soaps are sodium or potassium salts of long chain fatty acids. The action of a soap is based on the presence of both hydrophilic and hydrophobic groups in a soap molecule. This action emulsifies the oily dirt and helps in its removal.
The two ends of a soap molecule have different properties. When soap is added to water, the ionic, hydrophilic end of soap molecule dissolves in water. The hydrocarbon chain of soap molecule is hydrophobic and it dissolves in hydrocarbons i.e. links with oily dirt. The hydrocarbon chain of soap molecule orients towards the oil droplet while the ionic end orients towards water (polar solvent). This is how, soap molecules form structures called micelles where the oily dirt is collected in the centre. Thus, soap micelles help in dissolving dirt in water. Micelles stay in solution as colloids and the dirt suspended in the micelles is easily rinsed away.
Micelle formation will not take place in a solvent like ethanol because ethanol will dissolve the hydrocarbon chain of a soap molecule also.

Gandhiji’s three monkeys is a sculpture of three monkeys sitting together, one covering his eyes, one covering his ears and the other covering his mouth. It is a representation of the proverb ‘see no evil, hear no evil, speak no evil.’ In India, the sculpture was a symbol of ignoring the harsh and oppressive rule of the British.
According to some stories, Gandhiji kept a sculpture of the three monkeys with him, and this was one notable exception to his otherwise simple, no-possessions lifestyle. Soon, the sculpture became popular across India.
The Charkha
Search for a picture of Mahatma Gandhi on the Internet and you’re bound to stumble on to a photograph of him spinning khadi on his trusted charkha. To Gandhiji, the charkha embodied several things: Swadeshi, self sufficiency and even inter-dependency! Soon, the charkha was used all across the country as a major symbol of the National Movement.
The Azad Hind Flag
The Azad Hind or ‘Free India’ movement originated outside of India in the 1940s. Its chief architect was Netaji Subhash Chandra Bose. He sought to ally with the Axis powers of WW II and free India with the use of arms and ammunition.
This flag was used as the official emblem of the Azad Hind Fauj, more commonly known as the Indian National Army.
Recall the history of independence and the faces of eminent leaders will come to mind – Mahatma Gandhi, Jawaharlal Nehru and Bhagat Singh, to name a few. But do you know that several symbols played an important role in the movement too?
The Vande Mataram Flag
Some of you may remember reading about the ‘Swadeshi Movement’ in your history textbooks. It took place in 1905, after Bengal was partitioned by Lord Curzon, and continued until 1911. The movement was chiefly organised by the trio of Bal Gangadhar Tilak, Bipin Chandra Pal and Lala Lajpat Rai. The Calcutta Flag, designed during the course of this movement,sought to unite people from different religions, castes, etc.
