Question
Which of the following would most likely be reduced when combined with Al(s)?
- A. Fe
- B. K+
- C. H+
- D. Li+
Solution
To answer this question, we need to refer to the reduction potential chart. The reduction potential chart lists elements and their ability to be reduced (gain electrons). The higher the reduction potential, the more likely the element is to be reduced.
Here are the reduction potentials for the elements mentioned in the question:
A. Fe2+/Fe: -0.44 V B. K+/K: -2.93 V C. 2H+/H2: 0.00 V D. Li+/Li: -3.04 V
Aluminum (Al) has a reduction potential of -1.66 V.
In a redox reaction, the substance with the higher reduction potential is reduced, while the substance with the lower reduction potential is oxidized.
Since Aluminum (Al) is being combined with these elements, we are looking for an element that has a higher reduction potential than Aluminum (Al) and would therefore be reduced.
Comparing the reduction potentials, Hydrogen ion (H+) has a higher reduction potential than Aluminum (Al).
So, Hydrogen ion (H+) would most likely be reduced when combined with Aluminum (Al).
Therefore, the answer is C. H+.
