▁mole cules ▁that ▁have ▁dis soci ated . ▁It ▁is ▁usually ▁indicated ▁by ▁the ▁Greek ▁symbol ▁α . ▁More ▁accur ately , ▁degree ▁of ▁dis soci ation ▁refers ▁to ▁the ▁amount ▁of ▁sol ute ▁dis soci ated ▁into ▁ ions ▁or ▁radical s ▁per ▁mole . ▁In ▁case ▁of ▁very ▁strong ▁ac ids ▁and ▁bases , ▁degree ▁of ▁dis soci ation ▁will ▁be ▁close ▁to ▁ 1 . ▁Less ▁powerful ▁ac ids ▁and ▁bases ▁will ▁have ▁less er ▁degree ▁of ▁dis soci ation . ▁There ▁is ▁a ▁simple ▁relationship ▁between ▁this ▁parameter ▁and ▁the ▁van ▁' t ▁Hoff ▁factor ▁. ▁If ▁the ▁sol ute ▁subst ance ▁dis soci ates ▁into ▁▁ ions , ▁then ▁ ▁For ▁instance , ▁for ▁the ▁following ▁dis soci ation ▁K Cl ▁ ▁K + ▁+ ▁Cl − ▁ ▁As ▁, ▁we ▁would ▁have ▁that ▁. ▁ ▁Sal ts ▁See ▁also : ▁Sol ub ility ▁equilibrium ▁ ▁The ▁dis soci ation ▁of ▁sal ts ▁by ▁sol v ation ▁in ▁a ▁solution ▁like ▁water ▁means ▁the ▁separation ▁of ▁the ▁an ions ▁and ▁c ations . ▁The ▁salt ▁can ▁be ▁recovered ▁by ▁ev ap oration ▁of ▁the ▁sol vent . ▁ ▁An ▁electro ly te ▁refers ▁to ▁a ▁subst ance ▁that ▁contains ▁free ▁ ions ▁and ▁can ▁be ▁used ▁as ▁an ▁elect r ically ▁conduct ive ▁medium . ▁Most ▁of ▁the ▁sol ute ▁does ▁not ▁dis soci ate ▁in ▁a ▁weak ▁electro ly te ▁whereas ▁in ▁a ▁strong ▁electro ly te ▁a ▁higher ▁ratio ▁of ▁sol ute ▁dis soci ates ▁to
