Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid ...
Molecular models of the different molecules active in Piranha solution: peroxysulfuric acid (H 2 SO 5) and hydrogen peroxide (H 2 O 2). Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2).
Mineral acids are also used directly for their corrosive properties. For example, a dilute solution of hydrochloric acid is used for removing the deposits from the inside of boilers, with precautions taken to prevent the corrosion of the boiler by the acid. This process is known as descaling. [citation needed]
Oxidizing acids, being strong oxidizing agents, can often oxidize certain less reactive metals, in which the active oxidizing agent is not H + ions. For example, copper is a rather unreactive metal, and has no reaction with concentrated hydrochloric acid.
Sulfurous acid is commonly known to not exist in its free state, and due to this, it is stated in textbooks that it cannot be isolated in the water-free form. [4] However, the molecule has been detected in the gas phase in 1988 by the dissociative ionization of diethyl sulfite. [5]
The Ocean County Sheriff’s Office’s Drone Command Center, stationed right on Vision Beach in Seaside Heights, has three massive TV screens so deputies can track airplane traffic overhead ...
Oleum is a harsh reagent, and is highly corrosive. One important use of oleum as a reagent is the secondary nitration of nitrobenzene . The first nitration can occur with nitric acid in sulfuric acid, but this deactivates the ring towards further electrophilic substitution.
From February 2008 to May 2010, if you bought shares in companies when Kevin B. Rollins joined the board, and sold them when he left, you would have a 19.6 percent return on your investment, compared to a -13.7 percent return from the S&P 500.
