WebApr 10, 2024 · Answers (2) pH = −log [H+] , where [H+] denotes the molar hydrogen ion concentration. Notice that we are required to take the common (base 10) logarithm of the hydrogen ion concentration in order to calculate pH. My question then is how to solve the last line above without calculator in the hall. WebExplanation: The easiest and fastest way to calculate the value of log 5 is with the help of a logarithmic table. According to the logarithmic table, value of log 5 = 0.6990. Also, with the help of the logarithmic formula log (A/B) = log A - log B we can calculate value of log 5. As, log 5 = log (10/2)
