mol/L
Protons donated (acids), OH- released (bases), or electrons transferred (redox) per formula unit. HCl = 1, H2SO4 = 2, H3PO4 = 3, KMnO4 (acidic) = 5.

Your solution is 2.0000 N (2000.0 meq/L).

  • Normality counts reactive units (equivalents) per litre, so it is always molarity times the equivalence factor n.
  • For acids n is the number of H+ donated, for bases the number of OH-, and for redox reactions the electrons transferred per formula unit.
  • This solution is 2 N and 1 mol/L (M). They differ because each formula unit provides 2 equivalents.

Next stepDiluting this solution? Equivalents are conserved, so apply N1V1 = N2V2 to find the new normality after dilution.
