Question

Define chemical equivalent and electro chemical equivalent how they are related
B

Answer 1

Chemical equivalent is the weight in grams of a substance which displaces or combines with one gram of hydrogen. Chemical equivalent can be found by dividing the formula weight by its valence.

Electrochemical equivalent of a substance is the simple ratio of its chemical equivalent weight to a faraday.

ECE = E/F    

where E is Chemical equivalent weight, F is Faraday number.

Electrochemical equivalent or Eq of a chemical element is the mass of that element in grams which is transported by 1 coulomb of electricity. Eq is measured with a voltameter.
