The raw conductivity \\(\\kappa\\) measured by a conductivity meter depends on how much salt is dissolved, so a concentrated solution of a poorly conducting electrolyte and a dilute solution of a good one can give the same meter reading. Dividing \\(\\kappa\\) by the molar concentration \\(c\\) removes this ambiguity and tells you how effectively one mole of the substance carries electric current.<\/p>\n<p>The customary unit is S\u00b7cm\u00b2\/mol, which is what most chemistry textbooks and reference tables use. The SI unit is S\u00b7m\u00b2\/mol, and the conversion is simple: 1 S\u00b7m\u00b2\/mol = 10\u2074 S\u00b7cm\u00b2\/mol. The calculator displays both so you can match whatever your course or publication expects.<\/p>\n<p>Molar conductivity is most useful for studying <strong>strong<\/strong> and <strong>weak<\/strong> electrolytes. For strong electrolytes (NaCl, KCl, HCl), \\(\\Lambda_m\\) decreases only slightly with increasing concentration because ions remain fully dissociated and interionic attractions merely slow them down; the variation follows Kohlrausch's law \\(\\Lambda_m = \\Lambda_m^\\circ - K\\sqrt{c}\\). For weak electrolytes (acetic acid, ammonia), \\(\\Lambda_m\\) falls sharply with concentration because the degree of dissociation \\(\\alpha\\) decreases. The ratio \\(\\Lambda_m \/ \\Lambda_m^\\circ\\) approximates \\(\\alpha\\), which is the basis for determining dissociation constants \u2014 and by extension <a href=\"https:\/\/wpcalc.com\/en\/chemistry\/solubility-product-ksp-calculator\/\">solubility products<\/a> of sparingly soluble salts \u2014 from conductivity measurements.<\/p>\n<p>For orientation: at 25 \u00b0C the limiting molar conductivities \\(\\Lambda_m^\\circ\\) of common strong electrolytes fall roughly between 100 and 430 S\u00b7cm\u00b2\/mol (KCl \u2248 149.9; \u00bd H\u2082SO\u2084 \u2248 426). A result far outside this range usually signals a unit error rather than unusual chemistry.<\/p>\n<h2>Assumptions, Limitations and Practical Tips<\/h2>\n<ul>\n<li><strong>Conductivity must be specific conductance.<\/strong> The value you enter should already be corrected for the cell constant \u2014 i.e. what a calibrated conductivity meter displays, not the raw conductance.<\/li>\n<li><strong>Concentration refers to the formula unit.<\/strong> If the solution is labelled in terms of a fraction of the formula (e.g. \u00bd H\u2082SO\u2084), enter the concentration consistently with that definition, as reference tables do.<\/li>\n<li><strong>Temperature matters.<\/strong> Conductivity of aqueous solutions increases by roughly 2% per \u00b0C. Both \\(\\kappa\\) and \\(c\\) should refer to the same temperature \u2014 25 \u00b0C is the standard reference.<\/li>\n<li><strong>Check unit mix-ups.<\/strong> The most common errors are entering \u00b5S\/cm instead of mS\/cm, or mmol\/L instead of mol\/L. The calculator warns you when the result is implausibly large (&gt;500 S\u00b7cm\u00b2\/mol) or small (&lt;5 S\u00b7cm\u00b2\/mol).<\/li>\n<li><strong>Background conductivity.<\/strong> In very dilute solutions, dissolved CO\u2082 and solvent impurities contribute to \\(\\kappa\\) and inflate \\(\\Lambda_m\\); subtract the conductivity of the pure solvent if you work at micromolar concentrations.<\/li>\n<li>The calculator only computes \\(\\Lambda_m = \\kappa\/c\\). To extrapolate to infinite dilution \\(\\Lambda_m^\\circ\\) for a strong electrolyte, measure \\(\\Lambda_m\\) at several concentrations and fit against \\(\\sqrt{c}\\).<\/li>\n<\/ul>\n<h2>Typical Limiting Molar Conductivities at 25 \u00b0C<\/h2>\n<table>\n<thead>\n<tr>\n<th>Electrolyte<\/th>\n<th>\\(\\Lambda_m^\\circ\\) (S\u00b7cm\u00b2\/mol)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>KCl<\/td>\n<td>149.9<\/td>\n<\/tr>\n<tr>\n<td>NaCl<\/td>\n<td>126.5<\/td>\n<\/tr>\n<tr>\n<td>HCl<\/td>\n<td>426.2<\/td>\n<\/tr>\n<tr>\n<td>\u00bd H\u2082SO\u2084<\/td>\n<td>426<\/td>\n<\/tr>\n<tr>\n<td>CH\u2083COOH (weak)<\/td>\n<td>390.7<\/td>\n<\/tr>\n<tr>\n<td>NH\u2083\u00b7H\u2082O (weak)<\/td>\n<td>271<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values apply at infinite dilution; at finite concentrations the measured \\(\\Lambda_m\\) is somewhat lower.
