builds up, the battery will stop working — so we
use an electrolyte solution to balance the charge
back out.
Electrolytes are dissolved ions, charged
particles that can move freely through the
liquid. Sports drinks contain lots of electrolytes
to replenish our own supplies after a workout.
Sodium and potassium ions have positive charges
(we call these cations), while chlorides and
other anions have negative charges, all of which
are necessary to keep our cellular processes
working. These electrolytes are free to move
about in a liquid, meaning that positive and
negative charges can flow, creating electrical
current. Our bodies use these electrol ...
