WebHow are logarithms calculated? If you know the values of logp for every prime, these can be used to determine the logarithm of any positive rational number just by using the rules log(ab)=bloga and log(ab)=log(a)+log(b). And if you don’t remember what log(2) is, remember 210=1024≈1000, therefore 10log(2)≈3, or log(2)≈0.3. WebThe pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5. Similarly a pH of 11 is ten times more basic than a pH of 10.
