### Calculations using Nernst Eq.

What rules for natural logs are used when solving these equations where we solve for a missing PH or concentration? Im struggling with following the solution manual. Thanks!

### Re: Calculations using Nernst Eq.

the basic form of a natural log is ln(x) = y where e^y = x. From this, once you isolate the natural log, in order to find the concentrations inside the log (x), you should use this identity by setting both sides as exponents of the constant e

### Re: Calculations using Nernst Eq.

When you make both sides exponents of e, the ln in front of the concentrations cancel and you can solve the other side of the equation to get your answer.
