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.

Normally, the pH of water is a neutral value (or pH= 7). When \(\ce{NO_xs}\), \(\ce{SO_xs}\), \(\ce{CO}\), \(\ce{CO2}\) enter the water cycle, then the pH level is lowered below 7.0. If these gases are absorbed in rain clouds, then acid rain results.
