Hey everyone,

Say that I wanted to measure the Ni₂+ in water by using a nickel wire connected to a silver/silver chloride reference electrode...

A potential of .8 V is observed. How would I be able to ball park the Nickel 2+ concentration by using the nernst equation. Thanks.

E = E(AgSt.) - E(Ni0 +log(cNi))
Solve for cNi

E(AgSt.) and E(Ni0) find in tables.
