Analysis Method for pH and Alkalinity | Water Resources ...

When ,the pH, is above 7.0, the water is alkaline, or basic (there are more hydroxide ions than hydrogen ions). Since the scale is logarithmic, a drop in ,the pH, by 1.0 unit is a 10-fold increase in acidity. So, a water sample with a ,pH, of 5.0 is ten times as ,acidic, as one with a ,pH, of 6.0. ,pH, 4.0 is 100 times as ,acidic, as ,pH, …

Color is the main attraction of any fabric. No matter how excellent its constitution, if unsuitably colored it is bound to be a failure as a commercial fabric. Manufacture and use of synthetic dyes for fabric dyeing has therefore become a massive industry today. In fact the art of applying color to fabric has been known to mankind since 3500 BC.
