Answer:
OH−(aq), and H+(aq)
Explanation:
Redox reactions may occur in acidic or basic environments. Usually, if a reaction occurs in an acidic environment, hydrogen ions are shown as being part of the reaction system. For instance, in the reduction of the permanganate ion;
MnO4^-(aq) + 8H^+(aq) +5e-------> Mn^2+(aq) + 4H2O(l)
The appearance of hydrogen ion in the reaction equation implies that the process takes place under acidic reaction conditions.
For reactions that take place under basic conditions, the hydroxide ion is part of the reaction equation.
Hence hydrogen ion and hydroxide ion are included in redox reaction half equations depending on the conditions of the reaction whether acidic or basic.
Answer:
Explanation:
Option D electrolysis is the correct answer
Answer:
Explanation:
Any species that undergoes oxidation is itself a reducing agent or reductant.
The species that undergoes reduction in the course of a chemical reaction is an oxidant or reducing agent.
- Oxidation is defined as the loss of electrons, addition of oxygen and increase in oxidation number of a specie.
- Reduction is the gain of electrons, removal of oxygen and decrease in oxidation number of a specie.
Any specie that loses electrons to another undergoes oxidation and is a reductant.
Species that gains electrons are called oxidant.
