Chloride - Wikipedia
The chloride ion / ˈ k l ɔːr aɪ d / is the anion (negatively charged ion) Cl −.It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water.
Difference Between Chloride and Chlorate | Definition, …
9/2/2018· The chloride ion is given as Cl – and the chlorate ion is given as ClO 3 –. Both are able to undergo oxidation reactions because they can be further oxidized. The main difference between chlorine and chlorate is that chloride cannot undergo reduction reactions whereas chlorate easily undergoes reduction reactions.

Calcium The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns.

At a low pH, the coination of hydronium ion, H + and chloride, Cl-, ions will cause a very rapid corrosion. During storage, the pH of calcium chloride should always be kept at pH above 6.5. If a low pH is suspected, it should be measured, and a suitable base, i.e., NaOH or Ca(OH) 2 , should be added to increase the pH.

Ionic radius - Wikipedia
Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres with radii such that the sum of ionic radii of the ion and anion gives the distance between the ions in a crystal lattice.

Structural basis of α-amylase activation by chloride
Replacement of the chloride activator by a NO 3 − ion As shown in Table 1 1,, the binding of NO 3 − to AHA is 3 times stronger than that of Cl −, but only 45% of the maximal enzyme activity is restored.The stronger binding of NO 3 − compared with Cl − can be explained from the three-dimensional structure of the complex in terms of binding distances and geometry.
