3. The term mole is used in reporting text for amount Of
substance whereas mol is used for representing unit.
4. Analytical molarity (usually molarity) and equUibrium
molarity ate two different terms Equilibrium molarity
represents the mole of particular species in one litre of
solution.
S. The equilibrium molarity of a strong electrolyte is zero. F«
example consider analytical molarity of IM HCI.
equilibrium molarity of HCI is zero because of
1000
ionisation as
HCI —»yr+cr
whereas equilibrium molarities of H* and Cl- are IM each.
Similarly a solution of a strong electrolyte say Ax BY having
analytical molarity I M shows equilibrium molarities Of
AxBY , AY• and BX- as 0 M, XM and YM reqpctiv.ly.
6. Incase ofweak electrolytes (either a weak acid or weak base)
say analytical molarity of C M HA the equilibrium molarities
of HA, and A - are I — and Ca respectively since
it shows partial dissociation as ;
