Solution-Phase Chelators for Suppressing Nonspecific …
Protein−metal complexes may be transferred from solution into the gas phase by electrospray ionization (ESI), such that they can be directly analyzed by mass spectrometry (MS). In principle, therefore, ESI-MS represents a simple and elegant approach for gaining insights into the binding stoichiometry and affinity of these asselies. Unfortunately, the formation of nonspecific metal adducts

Corrosion of Zinc :: Total Materia Article
Groundwater also contains salts of calcium, magnesium, iron, and manganese. Seawater contains many of these salts in addition to its high NaCl content. All of these foreign substances in natural waters affect the structure and composition of the resulting films and corrosion products on the surface, which in turn control the corrosion of zinc.

GCSE Chemistry, Year 10, Preparation of Salts page
Salts - Solubilities (1) Preparation and solubility : Salts are prepared by reacting an acid with a metal or a base, such as a metal carbonate, hydroxide or oxide. The acid provides the non-metal ion for the salt, e.g. chloride or sulphate or nitrate ions. The metal or
Re-mineralization of Desalinated Water

General Characteristic Of Compounds Of Alkali Metals - …
Comparison of ionic and covalent character of alkali metal halides. When a ion approaches an anion, the electron cloud of the anion is attracted towards the ion and hence gets distorted. This effect is called polarization.
The Alkaline Earth Metals (Group 2)
As with the alkali metals, the atomic and ionic radii of the alkaline earth metals increase smoothly from Be to Ba, and the ionization energies decrease. As we would expect, the first ionization energy of an alkaline earth metal, with an ns 2 valence electron configuration, is always significantly greater than that of the alkali metal immediately preceding it.
Corrosion Effects of Magnesium Chloride and Sodium Chloride on …

In other words, the higher the RH, the lower the pollutant threshold concentration that can cause a metal to corrode. The deleterious effects of salt, oils and metal particulates are also greatly influenced by RH: Salts are hygroscopic and actively cause corrosion
Removal of Metal Ions from Wood Chips during Acidic …
It was, however, noted that part of the calcium in the wood material may be present in the form of salts of low solubility. Analyses imply that part of the calcium is present as calcium oxalate. When industrial wood chips were analyzed, the fraction of calcium present as calcium oxalate was found to be: 3% in Scandinavian softwood, 11% in birch and 16% in eucalyptus (E. globulus).

Why is calcium a metal? Why does it seem to have so …
Elemental calcium is indeed a metal, although a reactive one that tends to oxidize in air because of reaction with oxygen. The Ca 0 metal is not found often in nature for this reason. The "calcium" we talk about when we think of calcium scale on pluing is calcium carbonate , and other calcium salts.
