Water-soluble chloride ion (Cl-) content in concrete is expressed as a percent by weight of cement and is limited to a maximum amount by ACI 318. The water-soluble chloride ion content contributed ...

The positive and negative ions attract each other and form the ionic compound sodium chloride. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the ...

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

A dot and cross diagram for sodium chloride suggests that it is made up of pairs of sodium and chloride ions. It is not. A 3D construction model shows how the ions are arranged in a lattice structure.

This study makes the fundamental discovery of the first natural animal rhodopsin that uses a chloride ion instead of an amino acid side chain as a counterion. Using a combination of biochemical and ...

Carbonate ions also produce a white precipitate with barium chloride solution. The acid reacts with any carbonate ions present. This removes them, so stopping them giving a false positive result.

"We found that chloride ions present in the water enhanced the process by forming reactive molecular chlorine," Kong explained. "Our work provides a comprehensive assessment of using UV/chlorine ...
