Besides, is RO water acidic or alkaline?
Within about an hour, a glass of pure RO watercan drop from a pH of 7 down to a pH of 5.5 or lower and becomeacidic water. Alkaline water has a pH of greater than7, so reverse osmosis water is not alkaline water. Toalkalize it, you have to add calcium and other minerals toit.
Furthermore, what is the pH of RO water?
Reverse Osmosis water tends to be slightly acidic with apH of 5-6.
Water can be acidic or alkaline, depending on thesource. Reverse osmosis water purifiers will reduce thepH of drinking water. Because reverse osmosis removesthe minerals in water the water will then react with carbon dioxideupon exposure to air to form carbolic acids, thus lowering thepH.
