5.1. LOGARITHMS AND THEIR PROPERTIES. What is a Logarithm?. If x is a positive number, log x is the exponent of 10 that gives x . In other words, if y = log x then 10 y = x. log 100 = 2 because 10 2 = 100.

pH. Ionization of Water. When compounds dissociate/ionize in and aqueous solution, they produce ions - hydronium ( H 3 O + ) and hydroxide ( OH - ) T hese ion concentrations can be expressed more easily as [H 3 O + ] = 1.0 x 10 - 7 M and [OH - ] = 1.0 x 10 - 7 M.
