Chlorine compound, sodium chloride (table salt) has been known by human civilizations since prehistoric times and evidence of use of rock salt have been found from as early as 3000 BC . Elemental chlorine was isolated for the first time in around 1200, when aqua regia was discovered and was used to dissolve Nobel metals, like gold.

Angle-resolved XPS study of carbon steel passivity and …
1/5/2012· The passivity and chloride-induced depassivation of carbon steel in simulated concrete pore (CP) solution (pH = 13.3) was investigated using angle-resolved X-ray photoelectron spectroscopy (XPS). After full passivation, the thickness of the oxide film on steel
Chloride stress corrosion cracking in austenitic stainless steel
Chloride stress corrosion cracking (CLSCC) is one of the most common reasons why austenitic stainless steel pipework and vessels deteriorate in the chemical processing and petrochemical industries.
corrosion resistant steel – Instal
Steels 304 do not contain molybdenum, while 316 and 316L steels do. Addition of titanium to 18-8 steel enables carbon increase in the steel, decreasing the steel susceptibility to intercrystalline corrosion that follows formation of chromium carbides.
Deicers & Concrete Damage – Peters Chemical Company
The Federal Highway Administration conducted testing on salt, calcium chloride and magnesium chloride for freeze thaw damage following multiple cycles. The results are available by searching the Internet for SHRP Report C-391.
Corrosion of Steel in Concrete — What, Why, & How? – …
When chloride moves into the concrete, it disrupts the passive layer protecting the steel, causing it to rust and pit. Carbonation of concrete is another cause of steel corrosion. When concrete carbonates to the level of the steel rebar, the normally alkaline environment, which protects steel from corrosion, is replaced by a more neutral environment.

The inhibition properties of aspartic and lactic acid salts are compared with nitrite ions with regard to their effect on critical chloride concentration. The tests were carried out on carbon steel specimens in simulated pore solutions with initial pH in the range of 12.6 to
How can you identify a metal using a flame test? | …
Chemists use this same principle to determine the identity of unknown metals using a flame test. During a flame test, chemists take an unknown metal and put it under a flame. The flame will turn different colors based on which metal is in the substance. The
Calcium has four stable isotopes (40 Ca and 42 Ca through 44 Ca), plus two more isotopes (46 Ca and 48 Ca) that have such long half-lives that for all practical purposes they can be considered stable.It also has a cosmogenic isotope, radioactive 41 Ca, which has a half-life of 103,000 years. of 103,000 years.
Magnesium Chloride & Calcium Chloride are more widely used to de-ice roadways in winter conditions in the U.S. and Canada than Sodium Chloride (rock salt). After testing, it was found that Magnesium & Calcium Chloride dissolve, absorb & mix more easily with water helping protect roads much faster.
