Did you know?
WebSep 25, 2014 · Think of it this way: log (1) is 0 because we are at 1. Now when we move 1 decimal place to the left from 1.0 ---> 0.10, then we have log (0.1)= -1. Also, 0.1 is the same thing as 1x10^-1, so if you want to take the log of that then it would be -1 (just use the exponent, which shows its -1). WebDetermine the pH and pOH of a 0.0112 M Ba(OH)2 solution.
