FAQs on Electrochemistry in One Shot (NCERT) Video Lecture - Chemistry Class 12 - NEET
| 1. What is electrochemistry? |  |
Ans. Electrochemistry is the branch of chemistry that deals with the study of the relationship between electricity and chemical reactions. It involves the conversion of chemical energy into electrical energy or vice versa.
| 2. What are the applications of electrochemistry? | |
Ans. Electrochemistry has various applications in our daily life. Some of the common applications include electroplating, batteries, corrosion prevention, electrolysis, fuel cells, and sensors.
| 3. What is a redox reaction in electrochemistry? | |
Ans. Redox reaction, also known as a reduction-oxidation reaction, is a chemical reaction in which there is a transfer of electrons between two species. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced.
| 4. How does an electrochemical cell work? | |
Ans. An electrochemical cell consists of two electrodes (anode and cathode) immersed in an electrolyte solution. The anode is where oxidation occurs, and the cathode is where reduction occurs. When a potential difference is applied across the electrodes, electrons flow from the anode to the cathode through an external circuit, while ions flow through the electrolyte to maintain charge balance. This flow of electrons and ions creates an electric current.
| 5. What is the importance of electrochemistry in the field of medicine? | |
Ans. Electrochemistry plays a crucial role in various medical applications. It is used in devices such as pacemakers and defibrillators, which rely on electrochemical reactions to deliver electrical impulses to the heart. Electrochemical sensors are also used for detecting and monitoring various biomarkers and analytes in medical diagnostics. Additionally, electrochemical methods are employed in drug delivery systems and bioelectrochemistry research.
