The high value of the first dissociation constant maintains high concentration of Hþ ions in the
solution, and Hþ ions have a several-fold higher mobility than all other ions in the solution.
This guarantees high electrical conductivity of the H2SO4 electrolyte in the battery, which is
a mandatory requirement for any chemical power source.
The specific electrical resistance (resistivity) of the H2SO4 electrolyte is one of the basic
parameters that determines the inner resistance and power of a leadeacid cell.
