CBSE 2019 Class 12th Exam is approaching and candidates will have to make the … Hence conductivity of different electrolytes can only be compared if their solutions have equivalent concentrations. Importance of Electrochemistry 1. e.g. Electrochemistry Formulas for NEET The tendency of an electrode to lose electrons is called oxidation potential, while tendency to gain electrons is called reduction potential. Oxidation decreases concentration of chloride ions. NEET Chemistry Notes Electrochemistry – Electrochemical Cell Electrochemical Cell Electrochemical Cell An electrochemical cell or simply a cell is a system or arrangement in which two electrodes are fitted in the same electrolyte or in two different electrolytes which are joined by a salt-bridge. I'm uploading the simplest handwritten notes of Electrochemistry. The metal acquires a potential due to tendency of ions in one oxidation state to change into another stable oxidation state. Standard hydrogen electrode (SHE) also known as Normal Hydrogen Electrode (NHE), consists of platinum wire, carrying platinum foil coated with finely divided platinum black. Thus, : The higher the value of viscosity the lower is the value of, : The higher the value of dielectric constant of solvent, the more is the value of. Some commercial cells: Primary cells: Cells once exhausted cannot be used again e.g., dry cell and mercury cell. The transmission of sensory signals in our body from brain to other body parts takes place through neurons.
