Metals with a high positive value of standard electrode potentials:
Correct answer: D. Will not produce hydrogen with dilute acids
- A. Will produce hydrogen with dilute acids
- B. Will form a salt with acid
- C. None of these
- D. Will not produce hydrogen with dilute acids
Explanation
The arrangement of elements in order of increasing reduction potential values is called electrochemical series. The only metals that can liberate hydrogen from the acid are those with negative values of reduction potential i.e. -E0 values.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
