# Nickel and aluminum electrodes are used to build a galvanic cell. What is the theoretical cell potential assuming standard conditions? What is the shorthand notation for this cell?

##### 1 Answer

#### Answer:

See below:

#### Explanation:

List the 1/2 equations in order least positive to most positive:

Note we use the

The 1/2 cell with the most +ve

From this we can see that the 2nd 1/2 cell will be driven left to right and the 1st 1/2 cell right to left in accordance with the arrows.

So the 2 half - reactions are:

To get the equation to balance we need to X the first 1/2 equation by 3 and the 2nd half equation by 2 then add to get the overall cell reaction:

To calculate

The shorthand notation is:

Note the most oxidised form goes next to the salt bridge which is
