Detailed explanation-1: -Slippery Feel – Bases have a slippery feel. Many soaps and detergents contain bases. The slippery feeling of your shampoo is a property of the bases it contains. Reactions of Bases – Unlike acids, bases don’t react with metals.

Detailed explanation-2: -Bases feel slippery, like soap, and acids just feel wet. You shouldn’t touch either because they can damage your skin.

Detailed explanation-3: -Bases can change the structure of a protein. This property of base is what makes bases feel slippery. Soap is a base that, when it gets wet, feels very slippery on your skin. This same property to change the structure of proteins makes some strong bases very dangerous.

Detailed explanation-4: -Alkaline solutions are slippery or soapy to the touch, due to the saponification of the fatty substances on the surface of the skin. Alkalis are normally water-soluble, although some like barium carbonate are only soluble when reacting with an acidic aqueous solution.

Detailed explanation-5: -Soaps and detergents are strong bases, giving it a slippery feeling because bases react with molecules in your body called fatty acids. (If it was a strong acid, the soap would burn your skin.)
