Answer :
Final answer:
Sulfuric acid constitutes the largest percentage of an automotive battery electrolyte. Automotive batteries comprise six cells, with a cathode connected to a lead oxide plate and an anode connected to a lead plate, both immersed in sulfuric acid. Proper disposal of these batteries is essential due to their lead content.
Explanation:
The largest percentage of an automotive battery electrolyte is sulfuric acid. Automotive batteries, specifically lead-acid batteries, are often used due to their ability to produce the high current demanded by vehicle starter motors. These batteries comprise six galvanic cells, with each cell producing approximately 2 volts. This gives a total of 12 volts when the six cells are connected in series.
The cells contain a positive terminal (cathode) connected to a lead oxide plate and a negative terminal (anode) connected to a lead plate. Both these plates are immersed in sulfuric acid, which acts as the electrolyte for the system. The years of utilization of this technology signify its efficiency and reliability, despite the heavy weight and the caustic nature of the liquid electrolyte. Because the batteries contain significant amounts of lead, proper disposal is necessary for environmental protection.
