Electrochemistry class 12 Notes Chemistry chapter 3 in PDF format for free download. Electrodes-Made of porous graphite impregnated with catalyst (Pt, Ag or a metal oxide). electrodes to bring about the electrolysis and subsequent discharge of the ion on the electrode. These cells can be recharged and can be used again and again, e.g.. m cannot be obtained by extrapolating the graph. These are source of electrical energy which may have one or more cells connected in series. The dissociation constant (K) of the weak electrolyte at concentration C of the solution can be Barrier protection through coating of paints or electroplating. Important Questions for Class 12 Chemistry Chapter 3 Electrochemistry Class 12 Important Questions Electrochemistry Class 12 Important Questions Very Short Answer Type Question 1. In case of weak electrolytes, the degree of ionisation increases dilution which increases the Discharge potential is defined as the minimum potential that must be applied acrossthe vary appreciably during its use. and Λeq. Here are the Electrochemistry Notes for Class 12, JEE & NEET Exam Preparation eSaral helps the students in clearing and understanding each topic in a better way. When two or more ions compete at the electrodes. The conducting power of all the ions produced when 1 g-equivalent of an electrolyte is another metal that is more easily oxidised.
