CBSE Class 12 Ch 3 Electrochemistry Question and Answers With Notes
What is electrochemistry ?
Any It is the study of production of
production of electricity from energy
released during spontaneous chemical .
Q What is Reduction and Oxidation ?
Any Reduction It is the process in which an atom, ion or molecule gain one
or more e.g cud-1+2 eo → Cu
reduction It is the process in which an atom. ion or molecule lose one or more e e.g .zn
→ 2nd-1+200
Those Rxn in which oxidation as well as
reduction both takes lace simultaneously
G. Classify substances on the basis of electrical conductivity ?
And which allow electricity to pass through them
IN-sul.AT#:- which doesn't allow electricity to pass through them
sE_MlC0NDR:
-whose electrical conductivity lies b/w
conductor and Insulator. types → n type b- type .
Electrolyte
Those substance which dissociate into ions in their aqueous sun on passing electricity are known as electrolyte
Non Electrolyte :
Those substance which doesn't dissociate into ions in their aqueous solution on passing electricity is known as non Electrolyte Sugar, Urea,Glucose.
Factors Influencing Electrolytic Conduction :→ Nature of Electrolyte :large , the no. of ions ,more is conductance.
→ Nature of Solvent:
The electrolytes ionize in water but not in organic solvents like benzene because water is polar whereas benzene is non-polar . So , electrolytic conductance increase in polar solvents .
→ solute
-solvent attractions / Solvation or
Hydration : solvation of ions , lesser is conductance larger the → Temperature As the temp. increases, the conductance also increases because the dissociation of electrolyte increases. So , number of ions as well as the speed of ions increases. → Dilution : As dilution increases , the number of ions of a weak
electrolyte as well as their speed l increases and so conductance also increases .
Key Notes for CBSE based Class 12th Chemistry
The idea of electrochemistry combines chemistry and electricity. It discusses how chemical changes might result in the production of electricity. This article discusses the chemical reactions that happen when an electrolyte is sandwiched between an anode and a cathode in a battery. Students can better comprehend the chemical process in a battery that results in an electric current by using electrochemical reactions. The students may find this chapter challenging to comprehend and may require a lot of practice to grasp the concepts well.
