Heard of RO water…sound familiar…holly water perhaps…No its wonder water! All clean and ready to drink.
RO stands for Reverse Osmosis, separation process that uses pressure to force a solvent through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. In other word, its proses of water prurification (log on to http://www.en.wikipedia.com/, type RO water for further information).
Despite our dear Uncle Sam assuring that our water is clean, almost everyone knows that its lie. Pa tried fixing up a filter once, but it couldn’t be fixed. Hence, gave it to my uncle. We didn’t bother fixing up another one till Pa’s friend came to the house last weekend to introduce RO water.
He popped out the first golden question, “How clean is your water” and I confidently replied, “Its dirty”. He smiled. To show that our water was indeed dirty, he did some experiment. Yippy. I sure loved chemistry during high school, so waited eagerly for him to start.
First he asked us to fill up 3 glasses with water, tab, boiling and mineral water. He arranged it neatly on the table along with another glass filled with RO water. He then dipped the ph reader in each glass. The results:
Boiling water - 8 (yah, double!)
Mineral water - 14 (phew!)
RO water - 0
Tab water - Rustic and indescribable color
Boiling water - Less rustic but had green substance
Mineral - No dirt but all green, looked little like moss
RO water - Crystal clear
