Key Difference â Aggregate vs Average Aggregate and average are two terms that are often used in calculations. However, these two terms mean two different things. Aggregate refers to the total sum of elements in a data set whereas average refers to the central value in a dataset. This is the key difference between aggregate and average. What Does Aggregate Mean? Aggregate is an adjective and a noun which refers to something formed or calculated by the combination of several separate elements.
Hypochlorous acid and hypochlorite ions, when combined, is known as free chlorine. Both of these establish equilibrium and are both temperature and pH dependent at 7.5 pH and 77Â°F (25Â°C). Hypochlorous acid is more potent than hypochlorite ions in terms of disinfection.
State codes require that chlorine be injected into the pool water through the use of an approved automatic chlorinator. When chlorine (in any form) is added to water, a weak acid called Hypochlorous acid is produced. It is this acid, not the chlorine, which gives water its ability to oxidize and disinfect. Proper chlorination and filtration give pool water its clear, sparkling appearance. Chlorine exists as a solid, a liquid and a gas.
