Homework Help: chemistry (DrBob222)

Posted by Anonymous on Monday, November 21, 2011 at 1:31pm.

Calculate the value of Ecell for the reaction of cobalt(II) chloride and zinc metal, given the specific concentrations listed.

Zn(s) | Zn2+(0.21 M) || Co2+ (0.21 M) | Co(s)

Okay, so I keep getting -1.04 and -1.06 when I do this problem. I have used log k=-nEcell/0.0592 and then this other method i found where it told me to do something like K=0.0295/nxln

Please tell me what im doing wrong!
