why do we measure ph in water
Get to know the difference between pH paper and litmus paper. To obtain an accurate reading of a solution, you can use pH paper. This is not to be confused with the common litmus paper. Both can be used to test for acids and bases, but they differ in important ways. pH strips contain a series of indicator bars that will all change color after exposure to a solution. The strength of the acids and bases on each bar differs.
After they change, the color pattern of the bars can be matched to the examples that come with the kit. Litmus paper are strips of paper that contain an acid or a base (alkaline). The most common of these are red (which contains an acid that reacts with bases) and blue (which contains a base that reacts with acids).
The red strips turn blue if the substance is alkaline, and the blue strips turn red if they contact an acid. Litmus papers can be used to provide a quick and easy test, but the cheapest of them do not always provide accurate readings on the strength of the solution.
What is pH? pH (short for potential Hydrogen) is the measurement of acidity and its opposite, alkalinity in a solution.
Neutral pH is 7. 0 pH. Acidity measures below seven pH (7. 0pH) with alkalinity measuring above it (7. 0pH). Why is it important to measure pH? It is important to maintain a hydroponic nutrient solution at a pH level where the elements in the nutrient solution are consistently available to the plant. If the solution is too acidic or too alkaline it can cause lock up a situation which restricts certain elements essential for growth from being absorbed by the root structure.
Deficiencies in the required elements become apparent in the plants growth and can lead to crop failure. Additionally the pH of the water we drink is crucial to our health, the pH of a swimming pool is important, not only for our skin and eyes, but also for the efficiencies of sanitizers and pool equipment.
Again the pH of the water a fish lives and breeds in is critical to its existence as certain species require a particular pH to survive. The elements we add to a solution will either increase or decrease the solutions pH measurement. Only accurate measurement of the pH level will allow complete control of the outcome.
