How to find LOG on a scientific calculator


  
How to find LOG on a scientific calculator 
In my previous post I taught you how to use PH log and i think that it is quite important to know where it is on the calculator and how to find the button as someone like me whose first time using it was very confusing! But alas I got there:)
The opposite of log( is -10-x  X is the number that will always have a minus next to it, so don't forget to put the minus sign on it! it will also most likely have a decimal point in it too!

1.     pH=-log[H+]
2.     pOH=-log [OH-]3.     pH + pOH=144.     [H+]=2nd log (-pH)5.     [OH-]= 2nd log (-pOH)6.     [H+] x [OH-]=1X10-14

Log is a function on the calculator and stands for logarithm!



log on the scientific calculator looks like this:
