Why does charging lead acid battery give off hydrogen sulfide gas?
Wiki User
∙ 14y ago
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.

Charging a lead acid battery can cause electrolysis of the electrolyte solution, which can produce hydrogen gas. The presence of sulfur in the electrolyte can react with the hydrogen gas to form hydrogen sulfide gas. This reaction can occur if the battery is overcharged or if it is being charged at high temperatures.

What is the chemical name for fart acid?
The chemical name for "fart acid" is actually hydrogen sulfide (H2S). It is the compound responsible for the characteristic odor of flatulence.
Is hydrogen sulfide gas soluble in water?
Yes, hydrogen sulfide gas is soluble in water. It reacts with water to form hydrosulfuric acid, which is a weak acid. The solubility of hydrogen sulfide in water increases with decreasing temperature.
Are there carbon monoxide fumes from a battery charger?
Due to the chemical compositions of batteries (most batteries contain a form of acid which reacts to create electricity) neither the battery charger nor the battery is likely to produce CO (Carbon Monoxide)
What is the products of reaction of Borax with Hydrogen sulfide?
The reaction of borax (sodium tetraborate) with hydrogen sulfide would produce sodium sulfide and boric acid.
What type of reaction is fes 2hci feci2 h2s?
This is a double displacement reaction. Iron(II) sulfide (FeS) and hydrochloric acid (HCl) react to form iron(II) chloride (FeCl2) and hydrogen sulfide gas (H2S).
What type of gas is released when charging a lead acid battery?
hydrogen
What gas do you get from batteries?
Hydrogen is released during charging of a lead acid battery.
What hazardous gas will emit by lead-acid battery?
Hydrogen is released while charging.
Why should'nt any open flames be allowed when charging a battery?
A lead acid car battery releases hydrogen gas as it is charged. Hydrogen is highly flammable.
Can you smoke around a disconnected battery?
It's not healthy, but yeah. The trouble with a charging battery is hydrogen buildup from lead-acid (car) batteries.
Would hydrogen sulfide gas erode a plastic container holding the battery?
H2S is not likely to erode the plastic, but the acid from inside the battery definitely could.
Is hydrogen sulfide an acid or a base?
Hydrogen sulfide (H2S) is a weak acid. When dissolved in water, it can act as a weak acid, producing hydrosulfide ion (HS-) in solution.
How do batteries to produce hydrogen gas?
similar to separating the oxygen and hydrogen in water. When the battery fully charged it is made up of 64% water and 36% sulfuric acid and when the battery is in "charging" state by the alternator or charging source the electricity basically separates the water molecules (hydrogen from oxygen) giving of the hydrogen as bubbles.....sKD
What is the product of silver sulfide plus hydrochloric acid?
The reaction between silver sulfide and hydrochloric acid will produce silver chloride and hydrogen sulfide gas. Silver sulfide will react with hydrochloric acid to form silver chloride, which is a white solid precipitate, and hydrogen sulfide gas will be released in the reaction.
Is H2S a acid?
Yes, H2S (hydrogen sulfide) is an acid. It is a weak acid that can release hydrogen ions in solution.
Is H4S a base or acid?
H4S, or hydrogen sulfide, is a weak acid. When dissolved in water, it can ionize to produce hydronium ions and sulfide ions.
Can you smoke around disconnected batteries?
It's not healthy, but yeah. The trouble with a charging battery is hydrogen buildup from lead-acid (car) batteries.
