Does the electrolyte in a lead acid battery bubble and then evaporate due to the the heat change associated with the electrochemical reactions in the battery or is it something else?
I think its like the electrolysis of water where u get hydrogen bubbles....

The bubbles are hydrogen gas produced by the electrochemical reaction :
Explanation:
The hydrogen gas is doing something undesirable; it is coming out of aqueous solution and escaping as a gas. Modern Lead-Acid batteries are sealed so that most of the hydrogen gas remains in aqueous solution; this prolongs the life of the battery and increases its efficiency.
