Dear students, you can quote zeal in addition to the address: When two half of a cell of a type with different concentrations The electrolytes connect to each other, causing the cell to accu*ulate. In these cells, the half-cell is composed of a cathode and a half-diluted anode of the anode. In cathode cations, they absorb the electron and precipitate in the metal, and in the dilute metal (anode) cell, the metal enters the solution with the loss of electron in the cation. Therefore, with time, the concentration of the cathode solution decreases and the anodic solution concentration increases. The higher the concentration difference in the electrolyte solution, the higher the cell's efficiency. As time pas*es, due to the concentration of the two electrolytes, the voltage of the cell decreases until the electrolyte concentration is equal to two half of the cell, the flow in the external circuit of the final electrolyte concentration is equal to the average initial concentration in the two cathode electrodes. From this relation potential of one Concentration cell calculated. Determination of the reaction heat using a thermometer The heat of a reaction can be determined either directly or indirectly. In the direct method, some reactants should be affected in appropriate conditions and the reaction heat directly measured. For this purpose, a device called a thermometer is used. In indirect methods, the reactions with their heat
