WebbThe meter readings were noted for three pH buffers (viz. 4.0, 7.0 and 9.2) by turning the control knobs and bringing the readings to the nearest of the theoretical values of the pH buffers. The pH of nine other buffers and 20 natural water samples were measured and calculations were used to arrive at their correct pH values. Webb6 mars 2012 · 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 equivalent to a 10-fold increase in acidity. So, a water sample with a pH of 5.0 is 10 times as acidic as one with a pH of 6.0, and pH 4.0 is 100 times as acidic as pH 6.0. great clips mckinney hardinWebbJames C.
