It is defined as no. of equivalents of a solute present in one litre of solution
1. Equivalents and Meq. (milliequivalents) of reactants react in equal amount to give same no. of equivalent or Meq. of products separately.
2. Mole and millimole react according to balanced chemical equation.
3. Molarity x Valency factor = Normality
4. On diluting a solution, mole, mM, Equivalents and Meq. of solute do not change.
5. For reporting concentration of H2 02
direct conversions can be made as:
