Explanation:
Electrochemistry is the branch of physical chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice versa.
These reactions involve electric charges moving between electrodes and an electrolyte (or ionic species in a solution). Thus electrochemistry deals with the interaction between electrical energy and chemical change.
When a chemical reaction is caused by an externally supplied current, as in electrolysis, or if an electric current is produced by a spontaneous chemical reaction as in a battery, it is called an electrochemical reaction. Chemical reactions where electrons are transferred directly between molecules and/or atoms are called oxidation-reduction or redox reactions.
In general, electrochemistry describes the overall reactions when individual redox reactions are separate but connected by an external electric circuit and an intervening electrolyte.
Answer:
The study of the correlation between electrical energy and chemical changes is the focus of the branch of chemistry known as electrochemistry.
Explanation:
Electrochemical reactions are those in which electric currents are either generated or input. These responses can be roughly divided into two categories:
- The electrolysis phenomenon is the result of a chemical change being produced by electrical energy.
- Electricity is produced by spontaneous redox reactions or the transformation of chemical energy into electrical energy.
When electrons go from one element to another during specific sorts of reactions, electricity can result (such as redox reactions).
Electrochemistry often deals with the overall reactions when many redox reactions take place at the same time and are coupled by an appropriate electrolyte and an external electric current.
In other words, charge separation-related chemical processes are similarly studied by electrochemistry (as seen commonly in liquids such as solutions).
Charge transfer between various chemical species, whether homogeneously or heterogeneously, frequently occurs during the dissociation of charge.
Hence, the given statement is correct.
