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.
Chlorine was given its name in 1810 by Humphry Davy, who insisted that it was in fact an element. The pure chemical element has the physical form of a diatomic green gas. The name chlorine is derived from chloros, meaning green, referring to the color of the gas.t combines with inorganic material in water to form chloride salts, and with organic material in water to form chlorinated organic chemicals. Because of its reactivity chlorine is not likely to move through the ground and enter groundwater.
