Hemant Umre Sir explains key chemistry topics for exams like NEET and Class 12. He starts with electrodes—the spots where oxidation or reduction happens in a cell. Electrodes can be active (like zinc or copper, which join the reaction) or inert (like graphite or platinum, which don’t react).

Next, he covers electrode potential. When metals like zinc break into ions (Zn → Zn²⁺), electrons gather on the electrode, creating a potential difference between the electrode and solution. To measure this, scientists use the standard hydrogen electrode (SHE) as a reference (0.00 volts). Comparing other electrodes to SHE gives their standard electrode potential (E⁰). For example, zinc’s E⁰ is -0.76 volts.

Finally, Sir introduces the electrochemical series, which lists elements based on their standard reduction potentials. This series helps predict reaction outcomes and is crucial for understanding redox reactions in cells. He’ll explore this series in the next class.
