Why does charging lead acid battery give off hydrogen sulfide gas?
When a lead-acid battery is discharged, the electrolyte (sulfuric acid) and the active material on the plates of the battery (lead) are consumed to produce water and lead sulfate and current flow. The chemical equation for a lead-acid battery during discharge is: PbO2 Pb 2H2SO4 -->PbSO4 2H2O +Electrical energy. The chemical equation for a lead-acid battery during charge is the reverse with lead, sulfuric acid, and heat being yielded as well as some Hydrogen gas. Ideally, all of the lead sulfate is recombined with the hydrogen from the water to replenish the sulfuric acid. When a lead-acid battery is charged, electrical energy is added to the battery, causing the water and lead sulfate to be recombined to produce electrolyte and the active plate material. During normal charging, hydrogen gas is given off, however if internal damage to the plates or low electrolyte levels exist, internal gassing may create hydrogen sulfide gas. In sealed batteries this would normally not vent to the outside.

I think the answer is HS-1. This is written out in plain English (non-scientific terms) is HS Negative One. It may also be written as HS-
When cadmium sulfide is treated with sulfuric acid fumes of hydrogen sulfide are given off and express your answer in chemical formulas.?
CdS(s)+H2SO4(aq)--> Cd2SO4(aq)+H2S(g) one of the byproducts of this reaction will be gas Hydrogen Sulfide, H2S
Boron sulfide B2S3 reacts violently with water to form dissolved boric acid H3BO3 and hydrogen sulfide gas?
You are correct. Boron Sulphide will even react with atompheric water so has to kept away from air.
Battert Gases Vented Generally, automotive batteries discharge Hydrogen Gas during both the charging and discharge cycles.
What is the formula for Magnesium sulfide soldi and hydrochloric acid react to form hydrogen sulfide gas and magnesium chloride solution?
MgS(s) + 2HCl(aq) --> H2S(g) + MgCl2(aq)
it is a problem hydrogen sulfide gas is poisonous and should not be inhaled and should be avoided as much as possible
H2S is not likely to erode the plastic, but the acid from inside the battery definitely could.
It will more than likely explode. You charge the battery with a charger that coverts 120V AC to 12V DC.
Yes, well maybe. Not sure on jell cells. When you run current threw water though there is electrolysis and it splits into O2 and H2.
Charge them with a 6 volt battery charger.
