What produces hydrogen sulfide gas?

What produces hydrogen sulfide gas?

It is produced when bacteria break down plant and animal material, often in stagnant waters with low oxygen content such as bogs and swamps. Volcanoes, hot springs and underwater thermal vents also release hydrogen sulfide.

What gas is produced when H2S is burned?

When burning with oxygen, hydrogen sulfide burns blue, to form sulfur dioxide, and water.

What happens when lead acetate reacts with hydrogen sulphide?

Hydrogen sulfide reacts with lead ions from the lead acetate to form solid lead sulfide PbS, a black solid.

Where is H2S naturally?

It occurs naturally in crude petroleum, natural gas, and hot springs. In addition, hydrogen sulfide is produced by bacterial break- down of organic materials and human and animal wastes (e.g., sewage).

What happens when H2S is added to water?

H2S combines with water to form sulfuric acid (H2SO4), a strongly corrosive acid. Corrosion due to H2SO4 is often referred to as sour corrosion. Because hydrogen sulfide combines easily with water, damage to stock tanks below water levels can be severe.

What happens if you breathe in hydrogen sulfide?

At low levels, hydrogen sulfide causes irritation of the eyes, nose, and throat. Moderate levels can cause headache, dizziness, nausea, and vomiting, as well as coughing and difficulty in breathing. Higher levels can cause shock, convulsions, coma, and death.

How do you get rid of hydrogen sulfide?

Hydrogen sulfide may be reduced or removed by shock chlorination, water heater modification, activated carbon filtration, oxidizing filtration or oxidizing chemical injection. Often treatment for hydrogen sulfide is the same as for iron and manganese, allowing the removal of all three contaminants in one process.

What chemical smells like rotten eggs?

Hydrogen sulfide gas
Hydrogen sulfide gas (H2S) can give water a “rotten egg” taste or odor.

How do you test for hydrogen sulfide?

A suitable adsorbent paper is soaked in a solution made from bacteriological peptone, dipotassium hydrogen phosphate, ferric ammonium citrate, sodium thiosulphate; it is exposed to the water sample for 3 days, whereupon a black colour (and a smell of H2S) would demonstrate the presence of hydrogen sulphide-producing …

What is the formula for lead acetate?

Lead(II) acetate/Formula
