INTRODUCTION: To begin, it is required to understand water chemistry, and at It’s most basic level.

(1) [pic] Fig 1 Bohr model of H20 It is comprised of 1 Oxygen atom and 2 Hydrogen atoms. Now In reality we need to redefine the model because it actually “Exists” as free positively charged hydrogen ions (H+) and negatively charged hydroxyl ions (OH-). Andrews. etal (2004) [pic](2) Fig 2 Dissociation of water molecu le It is the ratio of these OH- ions and ! H+ ions that give us Acidity/alkalinity of a sample of water. I.E, if there are equal No’s the water is say to be neutral, if there are more than H+ ions The water is acidic, and if there are more OH- ions thusly alkali. “The degree of sullenness or alkalinity is measured on a scale Known as PH”. Templeton.R (2006). This is basically a Measure of the number of H+ ions...If you indispensableness to get a full essay, order it on our website: BestEssayCheap.com
