What is the application of Pb in the lead-acid accumulator?
a) The lead-acid accumulator is a voltaic cell that supplies electrical energy through electrochemical reactions.
b) The lead-acid accumulator consists of a set of unit cells formed by alternating plates of lead and lead dioxide, separated and supported by wood, glass wool, or fiberglass.
c) The lead-acid accumulator can be recharged by reversing the chemical reaction, which is achieved by forcing the passage of current through the cell in the opposite direction.
d) The electrolyte in a lead-acid accumulator is a 38% by weight sulfuric acid solution, which has a density of 1.29 g/ml.
e) The state of charge or discharge of the accumulator can be estimated by measuring the relative density (or 'specific gravity') of the electrolyte with a densimeter (or 'hydrometer').
