Lab Prodecure Question - To determine the standard Gibbs free energy for the dissolution of barium hydroxide, what materials would I need to use in the lab?
Homework Answers
Barium hydroxide (Ba(OH)2) dissociates in the aqueous solution, as shown below.
Ba(OH)2 ----> Ba2+(aq) + 2OH-(aq)
Here, Ba2+ will deposit on the cathode as barium metal (Ba).
Formula: 
Go =
-nFEocell
For the calculation of the Eocell, the electrochemical cell is required.
For the construction of the electrochemical cell, two electrodes (cathode and anode) are required.
And the salt bridge is required to connect both the electrodes.
Once, you find the Eocell, you can calculate the Gibbs free energy for the dissolution of barium hydroxide.

I cannot seem to figure it out.
The standard Gibbs-free energy of a system is related to its equilibrium constant through the following equation. AG = R.T.In(K) In this equation R is the gas constant, T is the temperature, and the next to AG defines the conditions as standard ambient temperature and pressure, i.e. "SATP".
