WebJul 21, 2024 · The scale ranges from 0 to 14 with the number in the middle (7) representing a point where the number of hydroxide ions and hydronium ions is equal. Substances with a pH of 7 are said to be "neutral." The pH scale is logarithmic, meaning that the difference in acidity or alkalinity from one whole pH value to the next changes by a factor of ten. WebFrom the change of base theorem, log base a of b = (ln b)/ (ln a). For example, you can calculate log base 3 of 5 by calculating (ln 5)/ (ln 3) which should give approximately 1.465. (Note that if your calculator also has a log key, another way to calculate log base 3 of 5 is to calculate (log 5)/ (log 3).
