What are the effects of sulfuric acid?
Most of the effects of sulfuric acid results from its strong acidity and large affinity to the water. Sulfuric acid corrosion is caused by its acidity. The effects of sulfuric acid on organic materials, including human tissue, are largely the result of its dehydration properties. Materials such as wood, paper and cotton substance are quickly burned when contact with acid. In this way, it will respond with many common metals, including iron, zinc and aluminum. The reaction is stronger with diluted acid than in concentrated acid. This limits the materials that can be used to store acid, although in a concentrated form it can be stored in stainless steel. The release of hydrogen gas is a potential risk of explosion in the event of leakage or leakage if ACID comes into contact with metals.
sulfuric acid is a very strong dehydration agent and a large amount of heat is released when contacting with water. If the VO isDa added to excess acid, the heat produced causes the water to boil immediately, which can lead to splitting the acid into a wide surface. For this reason, concentrated sulfuric acid should always be diluted by adding - slowly - to water; The process should never turn.
The dehydration effects of sulfuric acid explain its reactions with many common organic materials. It removes hydrogen and oxygen from the molecules that contain these elements in a ratio of 2: 1 found in the water molecule (H 2 o) - for example, carbohydrates - which include sugars, starch and cellulose. Sulfuric acid will react with carbohydrates to remove hydrogen and oxygen, leave behind the carbon. This illustrates well -known laboratory demonstrations; Concentrated sulfuric acid is added to sucrose sugar in the beaker and quickly converts it to the weight of coal, with a large amount of heat. That is why sulfuric acid rings wood and paper - substances that consist mainly of carbohydrates.
effects of sulfuric acid on the skinU are well documented and are again caused by dehydration properties of acid than its acidity. Skin contact with concentrated acid results in pain and swelling of tissue in seconds. If the contact is sufficiently extended, deep burns may occur and some commitment may occur, resulting in a brown color. As a result of the swelling caused, sulfuric acid burns often lead to permanent scarring.
When using sulfuric acid, suitable protective gloves and safety glasses should always be worn; A facial shield and a protective apron are also recommended. Small leaks for non -re -ed skin can be solved by fast washing with lots of water. Larger leaks are the risk of acid spraying if the water is immediately applied - it is better to quickly erase as much acid as possible before washing.
sulfuric acid is not volatile at room temperature and therefore usually does not pose an inhalation risk; If this acid or its industrial precursor, oxideSulfur comes into contact with water, the violence may cause gentle fog of sulfuric acid droplets. This can damage the eyes, airways and lungs if inhaled. Chronic exposure to sulfuric acid fog-for example in a sulfuric acid-sulfuric acid can have long-term health effects and may pose a risk of cancer for workers.
reaction of sulfuric acid with other materials can lead to dangerous products. For example, it releases toxic and corrosive vapors in contact with halogenides such as chlorides, fluorides and bromides. Schlorate and manganese contact produces strongly oxidative compounds that pose a risk of fire or explosion.
