· 2 Sulfuric acid is also formed when an aqueous solution of sulfur dioxide is oxygenated with oxygen, chlorine, bromine, nitrous acid or hydrogen peroxide. 2SO 2 + 2H 2 O + O 2 → 2H 2 SO 4. SO 2 + 2H 2 O + Cl 2 → H 2 SO 4 + 2HCl. SO 2 + 2H 2 O + Br 2 → H 2 SO 4 + 2HBr. SO 2 + 2HNO 2 → H 2 SO 4 + 2NO.
The invention relates to the technology of white Portland cement (BPC) and can be used at the final stage of the clinker burning bleaching. There is a method of bleaching clinker BOC (I), which consists in discharging the clinker from the sintering zone (temperature clinker 1420 o C) in a water bleach, representing a bath filled with water. The downside of it is the contact of hot …

The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a very weak fizz …
The calcite cement will react with hydrochloric acid and those sandstones with calcite cement will display effervescence. Additional possibilities: It is possible to use other carbonate minerals and produce the characteristic bubbles. Strontianite (strontium carbonate) is another mineral that reacts vigorously with 10% hydrochloric acid. Notes for demo tables: If you are doing …

In this second stage, the microbes accelerate the decline of the pH as they begin to produce sulfuric acid. Once the pH has been lowered to about 3, the acid will begin to corrode the cement binder in the concrete. As the pH drops even further, the corrosion accelerates and the sulfuric acid produced by the microbes converts the cement binder of concrete into non-load …
