In this post, I am sharing FSC 1st Year Chemistry Chapter 10 Solved Exercise PDF Notes for the students of FSC Part 1. The name of 11th Chemistry Chapter 10 is Electrochemistry. So the students can download Electrochemistry Chapter Solved Exercise in PDF format from here. This file contains 29 pages. These Chemistry Notes are for all the boards working under Punjab Board like Gujranwala Board, Lahore Board, Faisalabad Board, Multan Board, Rawalpindi Board, Sargodha Board, DG Kahn Board, and Sahiwal Board. Here are the complete 1st Year Chemistry Notes.

Which of the following statements is correct about galvanic cell?
a) anode is negatively charged
b) reduction occur at anode
c) cathode is positively charged
d) reduction occur at cathode
Stronger the oxidizing agent, greater is the,
a) oxidation potential
b) reduction potential
c) redox potential
d) E.M Fofcell
If a strip of Cu metal is placed in a solution of FeSO4:
a) Cu will be deposited
b) Fe is precipitated out
c) Cu and Fe both dissolve
d) No reaction take place
Fill in the blank.
The oxidation number of O-atom is +2 OF2 and is -1 in H2O2
Potential is setup when a metal is dipped in its own ions
If a fuel cell ,H2 and O2 react togather in the presence of KOH
What is the difference between single electrode potential and standard electrode potential? How can it be measured? Give its importance.
| Single electrode potential | Standard electrode potential |
| The potential setup, when an electrode is in contact with the solution of its own ions is called as single electrode potential. | The potential setup, when an electrode is in contact with one molar solution of its own ions at 298K and 1 atm pressure is called as standard electrode potential. |
| It is measured for any concentration of solution and at any condition of temperature and pressure | It is measured for one molar solution and at standard conditions of temperature and pressure. |
Measurement of electrode potential:
In any measurement of electrode potential, the concerned electrode is joined electrolytically with the standard hydrogen electron (SHE) and a galvanic cell is established. The two solutions are separated by a porous partition or a salt bridge containing a concentrated solution of potassium chloride, the salt bridge is used to provide a highly conducting path between the two electrolytic solutions. The potential difference is measured by voltmeter which gives the potential of the electrode, as the potential of SHE is zero. An oxidation or reduction may take place at SHE depending upon the nature of the electrode which is coupled with it.
