### I'm confused on the formula for calculating cell potential?

Posted:

**Wed Mar 14, 2018 10:01 pm**So on the equation sheet and in the textbook, it says the cell formula for calculating cell potential is

Eo= Eo (right electrode, cathode)- Eo (left electrode,anode)??

But then on other websites it says to find the standard cell potential you ADD them not subtract them ? Look at these websites:

http://www.chem.purdue.edu/gchelp/howto ... ntials.htm

and

https://www.chem.wisc.edu/deptfiles/gen ... /18_52.htm

I want to know because I am trying to solve 14.19
