Question

Which phrase best defines a redox reaction?
A. a reaction in which electrons are not transferred
B. a reaction in which electrons are transferred between different atoms
C. a reaction in which electrons are released from the system
D. a reaction in which the number of electrons atoms is reduced

Choose all correct answers

Answer 1

The best phrase that defines a redox (reduction-oxidation) reaction is:

B. a reaction in which electrons are transferred between different atoms

Additionally, it's important to note that in a redox reaction, one species gets reduced (gains electrons) while another gets oxidized (loses electrons), which is captured in option B.

The other options do not accurately capture the definition of a redox reaction:
A. is incorrect because redox reactions involve electron transfer.
C. is misleading; although electrons can be released during oxidation, it does not encompass the full definition of a redox reaction.
D. does not correctly describe a redox reaction as it doesn't specify the transfer of electrons between atoms, which is essential.

Therefore, the only correct answer is B.
