In other words, electrochemical equivalent or Eq of a chemical element is the mass of that element in grams which is transported by 1 coulomb of electricity. An equivalent (symbol: officially equiv; [1] unofficially but often Eq [2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. The formula for finding electrochemical equivalent is as follows: where is the mass of substance and is the charge passed. Books. Decomposition of a salt or other chemical compound by means of an electric current. i.e. Z= itm. Electrochemical equivalent = E / 96500 or, Z = E / F Also, Z = E / F.. (I) This is the required expression for the relation between faraday and electrochemical equivalent. The formula for finding electrochemical equivalent is as follows: = / 'k' is a constant that equals 0.0373100, 'A' is the gram-atomic weight and 'n' is the principle valence. Give the relationship between chemical equivalent and electrochemical equivalent of an element? See Faraday's laws. Advertisement Synonyms ECE, Eq Tags E = P M,P being the valence of atom involved. NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS Chauhan. As adjectives the difference between chemical and electrochemical is that chemical is ( label) of or relating to alchemy while electrochemical is (chemistry) of, or relating to a chemical reaction brought about by electricity. Electrochemical equivalents = kA/n Where k is a constant (0.0373100), A represents gram-molecular weight and n represents principle valence. Electrochemical equivalent is gram/coulomb. It is an archaic unit of measurement that was used in chemistry and the biological sciences (see Equivalent . chemical equivalent . The electrochemical equivalent, sometimes abbreviated Eq, of a chemical element is the mass of that element transported by 1 coulomb of electric charge. The mass of a given element liberated from a solution of its ions in electrolysis by one coulomb of charge. Numerous researchers have investigated electrochemical capacitors with PPy [22] , [23] due to its high conductivity, high storage ability, good thermal and environmental stability, high redox and capacitive current and . Conductance: - The current flowing through a conductor is given by, I = V/R Where, I= current in Ampere V= voltage in volt R= Resistance in ohm () A low resistivity indicates a material that readily allows electric current. The chemical equivalent can be described as the weight of one gram of substance which can displace with or combine with one gram of hydrogen and it can be found by dividing the weight of the substance by valency whereas the electrochemical equivalent is the ratio between the weight and charge passed. , and the electrochemical model's parameters have been tuned to match it. Conversion of these quantities is equally important as measuring them. More answers below Robert Gauthier Author has 10.7K answers and 3M answer views Feb 12 What is the electrochemical equivalent of a metal? 3.
