Titration is a method or process that is used to measure the various water balance levels in swimming pool water, such as pH, total alkalinity, and calcium hardness.
What is Titration for swimming pools?
Titration, also called titrimetry, is the manner of identifying the level or concentration of a certain substance in a solution. This process has been used as far back as the 18th century, with the aid of a burette, a device similar to that of a graduated cylinder. The titration method has been one of the most common means of water content identification practiced in laboratories across the globe.
For swimming pools, titration is the process used in test kits designed to measure pool water balance, plus identify concentrations of sanitizers like chlorine and bromine, along with metals such as copper. Test kits are readily available, and pool owners can do the testing themselves or hire the testing completed by a local pool maintenance service.
To titrate a water sample, add a pool water sample to the comparator tube commonly found in the test kit. Depending on the type of test, various reagents are added to perform chemical reactions that result in color changes to the water sample. Often, the number of drops and the resulting water sample color can be used to estimate chemical or contaminate concentrations in the pool water. With this knowledge, the pool tester can then adjust the water balance, chemical concentration, or sanitation steps to the swimming pool.
