pH Level - pH is a measure of how ‘acidic’ the water is in the pool. The pH scale runs from 0 to 14 and measure the acidity/alkalinity of the water. A pH value of 7 is neutral, a pH value below 7 is acidic and a pH value above 7 is alkaline. Water in the acidic range becomes increasingly corrosive as …

This means that water will have a pH equal to 7, whereas Sodium Hydroxide will be an alkali with a pH of 14. The lower the pH is, the higher the concentration of Hydrogen ions in the solutions’ dissolvent – meaning it is acidic.

If your ,water,’s ,pH, reading is naturally higher than a standard test can read, the High Range test will be essential. If your ,water, comes from a limestone aquifer, it could be over ,pH, 9.5. Extremely ,acidic water, samples may also not register on a standard ,pH, test, which may only go to ,pH, 6. In that case, a Wide Range test may be needed.

Conventional vacuum distillation systems adjust ,the pH value, before ,evaporation,. A side effect can be that boiling under vapour pressure can trigger after-reactions that deteriorate the distillate quality. Therefore, the Destcontrol process measures ,the pH value, not in the feed, but in the treated ,water, and reacts immediately.

17/5/2015, · No matter how much acid you add, for example, the pH will not change. That is, until the buffer becomes exhausted, at which point the solution will eventually turn acidic. Ideally, though, this point is never reached and the pH maintained. Addition or evaporation of water also do not markedly affect the pH of a buffer solution.
