for this problem. We're being asked to write an equation on how sulfuric acid will react with marble and limestone. And we're told that marble line stone are primarily calcium carbonate. So when we think about our reaction, we have calcium carbon et c a c 03 plus sulfuric acid, H two s four, and we're trying to figure out how it's going to react.

May 19, 2020· Based on the fundamentals of heterogeneous nucleation, a method to eliminate sulfuric acid aerosol associated with water recycling in the process of limestone-gypsum desulfurization was investigated. The supersaturated environment was achieved in a heat exchanger. Numerical calculation shows that high temperature drop and relative …

Dec 18, 2017· One of the many by-products of this sulfuric acid dissolution of limestone is a mineral called gypsum. Huge gypsum blocks still line the floor of the Big Room of Carlsbad Cavern. Other by-product minerals have been radioactively dated to show when this "sulfuric acid bath" occurred. It is now evident that Carlsbad Cavern was one of the last ...

However, sheltered areas on limestone and marble buildings and monuments show blackened crusts that have spalled (peeled) off in some places, revealing crumbling stone beneath. This black crust is primarily composed of gypsum, a mineral that forms from the reaction between calcite, water, and sulfuric acid.

Apr 17, 2016· My understanding is that sulfuric acid does at least affect limestone and marble, but as Klaus commented on marble, needs to have a resulting protective layer dealt with to continue dissolving. – ScottS. Apr 18, 2016 at 15:20. I don't think that someone tried to do serious research on dissolving the given types of rock in sulfuric acid.

Aug 25, 2020· Additionally, LC3 exhibited equivalent water absorptivity and resistance to acid attack compared to PPC. Micro-cracks were observed in SEM images from LC3 samples after immersion in acid. In conclusion, strength loss, at w/c = 0.50 and 0.60, LC3 exhibited 12.71 % and 14.06 % respectively, higher resistance to acid attack than OPC.

The SulfoLoop™ sulfuric acid plant produces concentrated commercial-quality H 2 SO 4 from concentrated non-condensable gases (CNCG) using the Wet-gas Sulfuric Acid (WSA) process developed by Haldor Topsoe, which uses catalytic conversion and condensation. Up to 99.9% of the sulfur in CNCGs can be converted into concentrated sulfuric acid …

Jul 01, 2020· The decomposition of limestone (CaCO3) to make lime (CaO) is also an endothermic process; it is necessary to heat limestone to a high temperature for this reaction to occur. How does acid affect limestone? When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite …

How fast does acid rain erode limestone? Pure water has a pH of 7.0 and does not dissolve limestone. Rain absorbs carbon dioxide from air forming carbonic acid giving rainwater a pH of 5.6 to 6. This slightly acidic solution slowly dissolves the limestone. Limestone caves take about 100,000 years to form.

Consequently, the hydrogen sulfide released from the agitated spring water is quickly re-absorbed into the oxygen-rich condensed water on passage walls, forming sulfuric acid. If the acid rests on a limestone wall, there is an immediate reaction between the acid and the limestone and moist acidic gypsum paste is formed. This reaction can be ...

Nov 19, 2012· Sulfur is one of the few elements that is found in its elemental form in nature. Typical sulfur deposits occur in sedimentary limestone/gypsum formations, in limestone/anhydrite formations associated with salt domes or in volcanic rock [].A yellow solid at normal temperature, sulfur becomes progressively lighter in color at lower …

However, we will be substituting this with vinegar. The technical way it affects the limestone is the neutralizing reaction (because vinegar is acid and limestone is alkali) is the CaC03( Calcium Carbonate) reacting with H2S04 (Sulfuric acid) = CaSO4 ( Gypsum) + H2CO3 ( Carbonic acid) results in production of CO2 gas.
