For example, suppose an ,acid, is added to water at 25°C and the ,acid, raises the H+ concentration to 1.0 x 10-4 moles/liter. Because [H+] [OH-] must always equal 1.00 x 10-14, [OH-] will be 1.0 x 10-10 moles/liter. pH is another way of expressing the hydrogen ion concentration. pH is defined as follows: pH = -log [H+] (2) Therefore, if the hydrogen ion concentration is 1.0 x 10-4 moles/liter ...

What is the pH Level of Water? For Tap Pure or Filtered Water

Acid Injection. The acid injection will treat, the water that has a high pH level by lowering the pH of the water to 7., This can eliminate the soda taste and now improve the effectiveness of chlorination. This can reduce the potential of pipe corrosion since water with a pH level above 9 can corrode metals like zinc, copper, brass, iron, and aluminum.

The ,acid, reacts with bicarbonate and carbonate ions present in the sample to release carbon dioxide (CO 2). The CO 2 released from bicarbonate and carbonate ions represents the TIC in the sample. The sample is then subjected to ultra-violet (UV) radiation, which reacts with the oxidant and breaks down all remaining carbon bonds in the sample to release CO 2 .
