Comment on the following observation: E 0 for M 2+ (aq) + 2e – → M (s) (where M = Ca, Sr, or Ba) is nearly constant.
Options
- AThis indicates that the standard reduction potentials of calcium, strontium, and barium are similar.
- BThis is because the electronic configuration of calcium, strontium, and barium is identical.
- CThis is due to the identical atomic radii of calcium, strontium, and barium.
- DThis suggests that the ionization energies of calcium, strontium, and barium are nearly the same.
Correct answer
A. This indicates that the standard reduction potentials of calcium, strontium, and barium are similar.
Step-by-step solution
Correct Option is : (A) This indicates that the standard reduction potentials of calcium, strontium, and barium are similar.
