Sulfuric acid comprises of sulfates. Its formula is H2SO4.
sodium, potassium, copper, ammonium, magnesium, etc. sulfates
Ferrous Sulfide = Iron (III) Sulfide Both -> Fe2S3
HgS, mercury(II) sulfide is formed, very insoluble.
Sulfate is a combination of oxygen and sulfur whereas sulfide is the negative ion of sulfur alone. Both are negative ions, anions.Both sulfur and oxygen are "hungry" for electrons. When they make a chemical bond it is to gain a share of electrons to put them into a more stable electron mode (or configuration). They each have six electrons in their outer energy level and they can also share electrons with each other. The sulfate ion that results is SO42- it allows both sulfur and oxygen to share enough electrons to have a stable electron configuration.Sulfur can also just gain two electrons to achieve a stable outer electron configuration, S2-. Compounds like H2S (rotten egg gas), hydrogen sulfide is a compound using sulfide.Na2SO4 , sodium sulfate or H2SO4 (sulfuric acid) are compounds using sulfate.P.S. the suffix '-ate' in chemistry indicates that there is oxygen present whereas '-ide' tells us that only the element alone is present in forming the ion.
Alkalis were first manufactured on a large scale as Sodium Carbonate in the 1700s using "The LeBlanc Process." This process mixed Sodium Chloride with Sulfuric Acid and then heated with charcoal and limestone. Byproducts included toxic gases Hydrogen Chloride and Hydrogen Sulfide.
using concentrated sulfuric acid.
Sulfuric acid does not melt metal, it oxidizes it and dissolves it. Aluminum will react with sulfuric acid, but because of the protective coating of aluminum oxide the reaction is extremely slow.
If you mean using it as a container, no. Sulfuric acid reacts with aluminum and so would eat through any container made of it.
Dihydrogen sulfate; it's known as sulfuric acid.

If by geothermal energy, you are referring to electricity produced using geothermal energy, no it doesn't smell, because energy in any form doesn't smell. On the other hand, a geothermal power plant may give off a "rotten eggs" smell. This is due to hydrogen sulfide being present in the steam collected from the geothermal reservoir. Although the hydrogen sulfide is treated to reduce it to non-toxic levels, hydrogen sulfide can be smelled at levels as low as a few parts per billion. Since geothermal plants won't always be able to remove all of the hydrogen sulfide, some will be released, accounting for the smell.
no it is a chemical change
