Using log10 ("log to the base 10"): where 10 is the base, 2 is the logarithm (i.e., the exponent or power) and 100 is the number. Using natural logs (loge or ln): Many equations used in chemistry were derived using calculus, and these often involved natural logarithms.... pH = -log[H +] Here it helps to rewrite the concentration as 1.0 x 10-4 M, because if you understand how logarithms work, this makes the formula: pH = -(-4) = 4 Or, you could simply use a calculator and take:
