Chapter 4: Problem 38

Is it possible to have a reaction in which oxidation occurs and reduction does not? Explain.

Short Answer

Expert verified
No, it is not possible to have a reaction in which oxidation occurs and reduction does not because these two processes are inherently linked. If something is being oxidized (losing electrons), then something else must be reduced (gaining those electrons).

Step by step solution

01

Understanding Oxidation and Reduction

Oxidation is a process where a substance loses electrons. Reduction is the opposite process where a substance gains electrons. In any chemical reaction, these processes always occur together. If a molecule is being oxidised, then it is losing electrons. These electrons can't just disappear - they must be gained by some other molecule, which is thus being reduced. Thus, both oxidation and reduction always happen together.
02

Applying the concept to the question

Thinking about these principles, if we have a reaction where something is being oxidised, this implies that something else has to be taking the electrons that are being lost. Thus, there is also a reduction process happening. So, it is not possible to have a reaction in which oxidation occurs and reduction does not.

A \(1.00-\mathrm{g}\) sample of a metal \(\mathrm{X}\) (that is known to form \(\mathrm{X}^{2+}\) ions) was added to a \(0.100 \mathrm{~L}\) of \(0.500 \mathrm{M}\) \(\mathrm{H}_{2} \mathrm{SO}_{4}\). After all the metal had reacted, the remaining acid required \(0.0334 \mathrm{~L}\) of \(0.500 \mathrm{M} \mathrm{NaOH}\) solution for neutralization. Calculate the molar mass of the metal and identify the element.
