What is osmosis? Also RO? And …

Thanks ? both of u.

Yes excellent Vikas

Good explanation!

Hmm in simple words! Suppose u have prepared some tea. U can't drink it directly as it will have tea leaves too. Now u will pass it through sieve.It won't happen itself, u have to do it i.e. u applied some pressure say. In the cup u will have tea and In the sieve there will be tea leaves and other insoluble components. This is what happens in Reverse osmosis. Here tea is solvent. Sieve serves as semipermeable membrane. Work done by u serves as pressure higher than osmotic pressure. Now for osmosis suppose I gave u two buckets which have water but not in equal amount. Suppose to balance the level of water u put some pebbles. But remember amount of water is still different. The bucket with more pebbles will have less water. Now suppose that there is 6 L water in one bucket and 4L in other total is 10L. I asked u to balance the amount. U filled 5L in each. Now both have equal water. This happens in osmosis. I know it is very long but it is simple. Ise pdhne ke baad Ek baar book se bhi pdhna. Na samjh Aaye to Phir se pdhna Aakhir me samjh aa jayega. Hope it will help.
