WebbThe Fahrenheit scale (/ ˈ f æ r ə n ˌ h aɪ t, ˈ f ɑː r-/) is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit.Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was … WebbWhen 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 6.0.
