Final answer:
The correct statements about oxidation based on the experiment are: (a) the metal changes from elemental form to ionic form in solution, (b) the metal loses electrons, and (f) the charge of the metal increases. Oxidation is associated with the loss of electrons and an increase in oxidation state.
Step-by-step explanation:
Based on the provided experiment observations and conclusions, the true statements about oxidation are:
- The metal changes from elemental form (a solid metal) to ionic form in solution, because it loses electrons and the charge of the metal increases.
- The metal loses electrons; as it does so, it gets oxidized, thereby increasing its oxidation number.
- The charge of the metal increases during oxidation due to the loss of electrons, resulting in an increase in the oxidation state.
Therefore, the correct answers are:
- (a) The metal changes from elemental form (a solid metal) to ionic form in solution.
- (b) The metal loses electrons.
- (f) The charge of the metal increases.
Conversely, incorrect statements regarding the oxidation process are:
- (c) The charge of the metal decreases - This is not correct because oxidation leads to an increase in charge, not a decrease.
- (d) The metal gains electrons - This statement describes reduction, not oxidation.
- (e) The metal changes from ionic form in solution to elemental form (a solid metal) - This also describes reduction, as it suggests the metal is gaining electrons and returning to its elemental form.
