Where is h2so4 found

Appearance: Clear colourless oily liquid. Yellow to dark brown in colour when impure. Odour: Odourless. Emergency Overview: Clear colourless oily liquid. Will not burn. Fatal if inhaled. Can form very hazardous decomposition products. Highly Reactive. Incompatible with many common chemicals.

Reacts violently with water. Causes severe skin burns and eye damage. Strong inorganic acid mists containing sulfuric acid are carcinogenic.

Sulfuric acid Group 1 - Carcinogenic to humans. Sulfuric acid A2 - Suspected human carcinogen. Inhalation: Take precautions to ensure your own safety before attempting rescue e. Move victim to fresh air. Keep at rest in a position comfortable for breathing. If breathing is difficult, trained personnel should administer emergency oxygen.

DO NOT allow victim to move about unnecessarily. Symptoms of pulmonary edema may be delayed. Immediately call a Poison Centre or doctor. Treatment is urgently required. Transport to a hospital. Skin Contact: Avoid direct contact. Wear chemical protective clothing if necessary. Quickly take off contaminated clothing, shoes and leather goods e. Quickly and gently blot or brush away excess chemical. Immediately flush with lukewarm, gently flowing water for at least 30 minutes.

If it can be done safely, continue flushing during transport to hospital. Double bag, seal, label and leave contaminated clothing, shoes and leather goods at the scene for safe disposal. Eye Contact: Avoid direct contact. Wear chemical protective gloves if necessary.

Quickly and gently blot or brush chemical off the face. Immediately flush the contaminated eye s with lukewarm, gently flowing water for at least 30 minutes, while holding the eyelid s open. Neutral saline solution may be used as soon as it is available. If necessary, continue flushing during transport to hospital. Take care not to rinse contaminated water into the unaffected eye or onto the face. Ingestion: Have victim rinse mouth with water.

If vomiting occurs naturally, have victim lean forward to reduce risk of aspiration. Have victim rinse mouth with water again. First Aid Comments: Some of the first aid procedures recommended here require advanced first aid training. All first aid procedures should be periodically reviewed by a doctor familiar with the chemical and its conditions of use in the workplace. It is generally considered stable and composed of sulfur, hydrogen, and oxygen.

The molecular formula for sulfuric acid is H 2 SO 4 , and it is water-soluble, meaning it will not burn. It is considered extremely corrosive due to its highly acidic nature and in high concentrations, it is dehydrating and oxidizing. Another interesting property that sulfuric acid exhibits its ability to absorb water vapor from the air, which means its hygroscopic. Because of this, it is highly reactive with most chemicals, especially water.

Sulfuric acid is a compound that is often found in acid rain which forms when atmospheric oxidization of sulfur dioxide occurs in the presence of water. Sulfur dioxide exists in the atmosphere as a byproduct of the burning of sulfur containing fuels, such as coal and oil.

Sulfuric acid also forms through the oxidization of sulfide-based minerals, like iron sulfide. The water by-product of this process is highly acidic and is called acid mine drainage. This stream is so acidic, it is capable of dissolving metals that are present in metal ores.

The result of this is brightly colored, highly toxic streams of water. Sulfuric acid is also produced industrially by oxidizing sulfur dioxide and using a number of different methods to collect the by-product — sulfuric acid. Sulfuric acid is a widely used and produced compound and there are several methods of production.

It is such a cornerstone in the industrial market that production of sulfuric acid typically goes hand-in-hand and with overall the overall industrial strength of a nation. It is also commonly used in the processing of petroleum refining and metallurgical processes. At home, you are most likely to encounter concentrated sulfuric acid in drain cleaner; when handling this common household chemical, it is important to always wear gloves and a mask to avoid negative long-term effects.

The biggest risk associated with sulfuric acid is its high level of corrosiveness. It tastes sour not that you would taste it in a laboratory! It turns blue litmus red except when it is the covalent molecule, i. Concentrated sulfuric acid is very hygroscopic. Its affinity for water is so great that if you left a beaker half full with conc. H 2 SO 4 for three weeks, its volume would greatly increase and it would become more dilute because it would have absorbed so much water vapour out of the air.

Firstly, add dilute HNO 3. Secondly, add Ba NO 3 2 aq. If sulfuric acid or a sulfate is present a white precipitate will be immediately observed. Hot concentrated sulfuric acid is an oxidising agent when it accepts electrons. The electrons are supplied by the reducing agent in the reaction:. Sulfur dioxide can be detected with a strip of filter paper moistened with potassium dichromate which turns from orange to green.

The misty fumes of hydrogen chloride gas are seen. The reason chlorine gas is not formed is because sulfuric acid is not powerful enough to oxidise chloride ions.

Bromide ions are a stronger reducing agent than chloride ions. As bromide ions are larger than chloride ions their electrons are easier to remove. Bromide ions reduce sulfuric acid into sulfur dioxide in two steps.

Iodide ions are even larger than bromide ions and iodides electrons are even easier to remove. Iodide ions will reduce concentrated sulfuric acid into hydrogen iodide gas, which will further reduce sulfuric acid in three ways at room temperature. Concentrated sulfuric acid is very good at removing the water from sugars. When the elements of water are removed from sucrose it leads to a black mass of carbon see photo, left and the Molecule of the Month page on glucose.

Sulfuric acid can also be used to dehydrate sodium salts of some carboxylic acids. This use of sulfuric acid has already been mentioned in the Molecule of the Month page on Carbon monoxide.
