Web16 de out. de 2016 · The ionic strength of 0.0087 mol/L #"NaOH"# is 0.0087 mol/L. Explanation: The molar ionic strength , #I# , of a solution is a function of the concentration of all ions in that solution. 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. Its normality is about 0.154 N. Ver mais Normality is defined as the number of gramme or mole equivalents of solute present in one litre of solution. The SI unit of normality is Eq/L. Normality formula Normality (N) = Mass of Solute (in gm) / (Equivalent Weight … Ver mais Normality is an ambiguous measure of the concentration of a given reagent in solution.
