A measure of the acidity\/alkalinity of a solution.<\/p>
The pH is generally on a scale that ranges from 0 (maximum acidity) to 14 (maximum alkalinity).<\/p>
The following are common pH values.<\/p>
NEUTRAL pH<\/p>
– Distilled water at 25\u00b0C (pH 7)<\/p>
– Human saliva (pH 6.5 \/ 7.5)<\/p>
ACIDIC pH<\/p>
– Vinegar (pH 2.9)<\/p>
– Coca Cola (pH 2.5)<\/p>
– Hydrochloric acid (pH 0)<\/p>
ALKALINE pH<\/p>
– Alkaline soaps (pH 9 \/ 10)<\/p>
– Bleach (pH 12.5)<\/p>
– Sodium hydroxide (pH 14)<\/p>
In ceramics, for example, the pH of process water is a very important value that must be checked. The grinding water mixed with clays during the slurry's preparation must have the right features to ensure a proper development of the following phases. pH is of course, one of these features. A too acidic pH (the proper value usually is about 8.5 \/ 9) could negatively act on the slurry's viscosity and therefore on its correct flow.<\/p>","protected":false},"excerpt":{"rendered":"
