Redox Reactions And Electrochemistry Ques 564
Question: The standard electrode potentials $ ( E{{{}^\circ }_{{M^{+}}/M}} ) $ of four metals A, B, C and D are $ -1.2V,0.6V,0.85V $ and $ -0.76V, $ respectively. The sequence of deposition of metals on applying potential is:
Options:
A) A, C, B, D
B) B, D, C, A
C) C, B, D, A
D) D, A, B, C
Show Answer
Answer:
Correct Answer: C
Solution:
[c] As the value of reduction potential decreases the reducing power increases i.e. $ \begin{aligned} & ,C,<B,<D<\text{ }A \\ & ( 0.85 ).( 0.6 ).( -0.76 )( -1.2 ) \\ \end{aligned} $
