"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. Properties of the pH Scale " - How are logarithms calculated

Real numbers are almost universally represented in terms of a mantissa and an exponent: x = m *2 p, where p is an integer and m is between 1 and 2. Thus log ( x) = log ( m )+ p *log (2). The latter term, p *log (2), is just a multiplication by a known constant.
