What is meant by electrochemical equivalent?
Define Faraday's first law of electrolysis.
What is a secondary battery? Give one example.
What is fuel cell? Write its main advantage.
Define corrosion and give a chemical example.
What is meant by limiting molar conductivity?
Why does the molar conductivity of a weak electrolyte increase sharply on dilution?
What is a primary battery? Give an example.
Explain Kohlrausch's Law of Independent Migration of Ions in detail. Discuss its various applications, particularly how it is used to calculate the limiting molar conductivity of weak electrolytes like acetic acid, with proper mathematical expressions.
What are primary and secondary batteries? Explain the structure, operation, and chemical reactions of LeclanchΓ© cell (dry cell) and lead-storage battery with suitable equations.
Calculate the EMF of the cell in which the following reaction takes place: $Ni(s) + 2Ag^+(0.002 M) \rightarrow Ni^{2+}(0.160 M) + 2Ag(s)$\nGiven that $E^0_{cell} = 1.05 V$. (Use Nernst equation, $F = 96500 C mol^{-1}$, $log 2 = 0.3010$, $log 10 = 1$)
Define Electrochemical Cell and Electrolytic Cell. Explain the construction and working of a Galvanic cell (Daniel cell) with proper chemical reactions and half-cell representations.
