Water PH Test2011-2-26 11:49:23
water ionizer separates water into alkaline and acid fractions, what does pH mean for water? Basically, the pH value determines whether water is hard or soft. The pH of pure water is 7. In general, water with a pH lower than 7 is considered acidic, and with a pH greater than 7, basic. The normal range for pH in surface water systems is 6.5 to 8.5 and for groundwater systems 6 to 8.5. Alkalinity is a measure of the capacity of the water to resist a change in pH that would tend to make the water more acidic. The measurement of alkalinity and pH is needed to determine the corrosiveness of the water.
1 Pour a glass of water. Let the water sit for about a minute to ensure there is no underlying current or associated ripples from filling the glass.
2 Open up your container of pH testing strips with dry hands in a relatively dry environment; make sure you never expose unused pH testing strips to water, otherwise the color-coding on these strips will activate, and the strips will be useless for future testing.
3 Dip the pH test strip into the water; avoid stirring or splashing the water if at all possible.
4 Hold the pH test strip under the water for several seconds. Depending on the brand of test strip you are using, submersion times will vary; consult the packaging for exact guidelines.
5 Remove the pH strip after submersing for the recommended duration. Hold the test strip level and wait a 5 to 10 seconds for the strip's color swatches to brighten.
6 Compare the colors on the strip to the guide printed on the pH testing strip container. Different color shades indicate different acidity or basicity levels.
7 Throw away the used pH test strip once you are finished. Testing strips are designed for single-use only.
