Question

why citric fruits use to clean something??why oranges and lemons are used in facewashes or use for cleaning tan?? explain how.....

Answer 1

As you probably know if you've ever bitten down into a citrus fruit , these fruits are pretty sour. Chemically speaking, what your tongue interprets as sour is citric acid. Lemons are quite acidic — more acidic than orange juice and black coffee, although not quite as acidic as your stomach juices — and this is the key to their effectiveness as cleaning agents.

Although many types of soap are alkaline (i.e., not acidic), acids can be pretty useful when it comes to cleaning. They can eliminate stains caused by other acids, or combine with alkaline compounds to create powerful chemical reactions.

Hope it helps you buddy..
