Normality can be used for acid-base titrations. For example, sulfuric acid (H2SO4) is a diprotic acid. Since only 0.5 mol of H2SO4 are needed to neutralize 1 mol of OH , the equivalence factor is: feq(H2SO4) = 0.5 If the concentration of a sulfuric acid solution is c(H2SO4) = 1 mol/L, then its normality is 2 N. It can … Ver mais In chemistry, the equivalent concentration or normality (N) of a solution is defined as the molar concentration ci divided by an equivalence factor feq: Normality = ci/feq Ver mais There are three common types of chemical reaction where normality is used as a measure of reactive species in solution: • In Ver mais • Equivalent (chemistry) • Normal saline, a solution of NaCl, but not a normal solution.
