Why Calcium Montmorillonite Clay Doesn’t Work – …

22/06/2015· Why, because there are week bonded calcium ions that will exchange with what is in the water. It is that exchange potential that must be guarded and preserved before appliion. Virus, fungi, bacteria, and heavy metals have a positive charge which will “use up” the available space which carries the ionic potential of the clay.

introducing transition metals - chemguide

These are used to form co-ordinate bonds with the metal ion. Some examples of complex ions formed by transition metals [Fe(H 2 O) 6] 2+ [Co(NH 3) 6] 2+ [Cr(OH) 6] 3-[CuCl 4] 2-Other metals also form complex ions - it isn''t something that only transition metals do. Transition metals do, however, form a very wide range of complex ions.

[Solved] Flame test lab 1.Why do you think we use …

Metal salts are used rather than the pure metals because the metal salts are more stable and less reactive than the pure metals. For example, some metals like sodium and potassium are extremely reactive with water and could potentially react with any water vapor present in the air so the metal salts are used instead. 2.
