Total alkalinity, unlike pH, is a quantitative measurement. Total alkalinity is the measure of carbonate and bicarbonate present in the water. This is measured in units of parts per million(ppm), and in terms of calcium carbonate. [For example, ] 10ppm total alkalinity=10 lbs calcium carbonate in 1, 000, 000 lbs of pure water.  3, record 1, English, - total%20alkalinity

Contrairement au pH, l'alcalinité totale est une mesure quantitative. L'alcalinité totale correspond à la teneur de l'eau en carbonates et en bicarbonates de calcium. Cette quantité est exprimée en parties par million (ppm). Par exemple, une alcalinité totale de 10 ppm correspond à 10 lb de carbonates de calcium dans 1 000 000 lb d'eau pure.  2, record 1, French, - alcalinit%C3%A9%20totale

A measurement of the completeness of an incomplete chemical reaction. It is defined as the negative logarithm(to the base 10) of the equilibrium constant, K, for the reaction in question. The pK is most frequently used to express the extent of dissociation or the strength of weak acids... In a solution of weak acid, if the concentration of undissociated acid is equal to the concentration of the anion of the acid, the pK will be equal to the pH.  1, record 3, English, - pK

The earliest enzyme electrodes consisted of an electrochemical sensor, a semipermeable membrane and an intermediate layer containing the enzyme. This system required diffusion of the substrate through the membrane, there to react with the enzyme and so causing production or consumption of a material which was then measured by the electrochemical sensor....

The PREPA facility produces 20 percent of the island's steam generated electricity. The plant uses nearly 1. 3 million gallons of water daily. This torrent is processed by four boilers enabling four steam units to produce 602 megawatts of power. However the Puerto Rican water company supplies water with a mineral concentration of 200 parts per million(ppm). Injecting such water at a high temperature directly into the boilers could destroy them immediately. So a demineralizing plant must purify the water using resin beds and employing control based on the measurement of such factors as conductivity pH soda and acid concentration.  1, record 7, English, - demineralizing%20plant
