Concentrated sulfuric acid has a specific gravity of 1.84 while the specific gravity of distilled water is 1.00. When the sulfuric acid is diluted with water to make the battery electrolyte, the specific gravity of the end product should be between 1.26 and 1.30.
Lead-Acid Battery Specific Gravity. When a lead-acid battery is in a nearly discharged condition, the electrolyte is in its weakest state. Conversely, the electrolyte is at its strongest (or greatest density) when the battery is fully charged. The density of electrolyte related to the density of water is termed its specific gravity.
The lead-acid battery with sulfuric acid just undergoes reactions involving the lead and gives contained, nonvolatile products. By way of contrast, hydrochloric acid could be oxidized to chlorine gas at the anode and nitric acid could be reduced to nasty nitrogen oxides at the cathode.
Basically, when a battery is being discharged, the sulfuric acid in the electrolyte is being depleted so that the electrolyte more closely resembles water. At the same time, sulfate from the acid is coating the plates and reducing the surface area over which the chemical reaction can take place.
In a lead acid battery, the electrolyte is a mixture of water and sulfuric acid. This mixture allows for a chemical reaction to take place between the lead in the electrodes and the sulfuric acid, which creates an electric current. The electrolyte also helps to keep the ...
