De-Ionized water is exactly what it sounds like: it is water that has had the ions removed. For instance, tap water usually contains many ions from the pipes, soil, and other sources. These can include sodium, calcium, iron, and copper ions. De-ionized water would remove these ions from the water.
How Water Becomes Ionized
Substances that dissolve in water ionize the water; therefore, all water that you find in nature is ionized. For example, when salt (NaCl) is deposited into water, the atomic bond between the sodium and chloride atom loosen up but do not separate because they are have a positive charge, and charged particles are called ions. Consequently, salt in water is ionized water.
Why Are Ions Removed From The Water?
When water is de-ionized it has relatively the same purity that distilled water has, but the process does not remove viruses or bacteria from the water. There are many people who claim de-ionized water has health benefits. There has been no proof of this to date. Moreover, even if it did have health benefits, the fact is that most of the ions removed from the water are regained while eating foods that have been made with or contain water that has not been de-ionized.
Other purposes for de-ionizing water, besides for drinking, are organic chemistry (to remove the interference that ions can have with chemical processes) and battery water refill.
Should You Drink De-Ionized Water Or Ionized Water?
There are many people, including Bill Clinton, who say that ionization of water can result in improved energy, promote better digestion, aid in chronic conditions, and improve overall health. Even the Japanese and Korean ministries of health have approved water ionizers as a medical device. Still other people say that ionized water doesn’t have any major health benefits, and that it is a hoax.
Research has been done, and the health claims of ionized water are that it can help you fight a wide variety of issues including arthritis, digestive problems, weight problems, diabetes, cancer, gout, allergies, chronic pain, and much more.
So, should you drink de-ionized water or ionized water? It depends whether or not you believe the health claims made by users of either way.
There is no proof that de-ionized water has health benefits, whereas there have been studies that show ionized water had a positive effect on things such as cancer. In addition studies have shown ionized water to have anti-oxidant, anti-microbial, and anti-bacterial properties. Another thing to take note of is that de-ionized water cost more and will put a bigger dent in your wallet.
