Stuck with a problem in electrochemistry

In summary, a galvanic cell with two silver electrodes in saturated solutions of AgBr and Ag2CrO4 is prepared. Using the Ksp values of both solutions, the concentration of Ag+ in each solution is calculated. The Nernst equation is then used to find the value of Ecell at 298K, with the potential reported as positive. The value of E0 is not taken into account, but technically should use the value for the Ag(s)/Ag+ system.

The Attempt at a Solution



I got the conc of Ag+ in both the solutions ... but i don't know how to substitute them...(means ...i don't know which comes in the numerator of the logarithm)
and Is the value of E0 to be taken as 0? How ?

pls help...

thanks in advance:smile:

Report the potential as positive. E0 cancels out, but technically you should use value for the Ag(s)/Ag+ system.

thank you sir...

i am getting it now...:smile:
 

1. What is electrochemistry?

Electrochemistry is a branch of chemistry that deals with the study of the relationship between electricity and chemical reactions. It involves the use of chemical reactions to produce electrical energy or the use of electrical energy to drive non-spontaneous chemical reactions.

2. What are some common problems encountered in electrochemistry?

Some common problems encountered in electrochemistry include electrode fouling, corrosion, and low cell efficiency. Other issues may include inaccurate measurements or unstable electrode potentials.

3. How do you troubleshoot a problem in electrochemistry?

The first step in troubleshooting a problem in electrochemistry is to identify the specific issue. This can be done by carefully examining the experimental setup, checking for any signs of electrode fouling or corrosion, and verifying the accuracy of measurements. Once the issue is identified, it can be addressed with appropriate solutions such as electrode cleaning or adjusting experimental conditions.

4. What are some techniques used in electrochemistry to improve accuracy?

Some techniques used in electrochemistry to improve accuracy include calibration of instruments, controlling experimental conditions, and using appropriate reference electrodes. It is also important to carefully follow experimental protocols and minimize sources of error.

5. What are some real-world applications of electrochemistry?

Electrochemistry has a wide range of real-world applications, including batteries and fuel cells for energy storage and conversion, electroplating for metal coating, and corrosion prevention in infrastructure such as bridges and pipelines. It is also used in analytical chemistry for determining the concentration of ions in solution and in pharmaceuticals for drug delivery.
