Is water acidic or basic?
Pure water is neutral, with a pH of 7.0. When chemicals are mixed with water, the mixture can become either acidic or basic (alkaline). Vinegar and lemon juice are acidic substances, while laundry detergents and ammonia are basic (alkaline). Chemicals that are very basic or very acidic are called “reactive.”.
Is a pH of 7 acidic?
A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline). Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6.
Is acidic water corrosive?
Acidic water is corrosive. Alkalinic water is more prone to scaling. Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3) and hydroxyl (OH) ions in the water. pH and alkalinity ratings are NOT the same and are NOT proportional. pH is rated on the Scale and alkalinity is measured in parts per million (ppm).

What happens when the phosphorus limit is lowered?
As the phosphorus limit is lowered, the corresponding amount of these coagulants required increases to 4 or more molecules of coagulant for every molecule of phosphate removed. That is a lot of acid! Your pH tips strongly to the acidic side and if you don’t balance it out, your treatment is compromised. To pull your pH back into the neutral range ...
What pH level is phosphorus?
Traditional phosphorus removal coagulants, using aluminum or iron-based salts, are strongly acidic with a pH level of 1.5 to 2.2.
Is caustic acidic coagulant dangerous?
The acidic coagulant is extremely irritating to skin, eyes and lungs, and the caustic is just as dangerous. If you mix caustic yourself from bags, it is a very hazardous operation. Once you have it mixed, even the most dilute solution has a high freezing point, which means you must keep the tank and pipes heat traced.
Is Neo Waterfx acidic?
For starters, Neo WaterFX is less acidic, with a pH between 3 and 4. Now you may say, but wait a minute, that is still acidic, and you are right. But remember that pH is a logarithmic scale, so the difference in 2 in your pH, say between 4 and 2, means 100 times LESS acid.
