Meanwhile, the copper(II) ions from the solution are reduced to copper metal, which eventually causes the blue copper(II) sulfate solution to become colorless. The process that occurs in this redox reaction is shown below as two separate half-reactions, which can then be coined into the full redox reaction.

How do you write an ionic equation for the following …

2018/8/8· How do you write an ionic equation for the following reaction? A student repeats the experiment with copper instead of magnesium. State whether a reaction would still occur. Steps for rewriting this chemical equation in its ionic form: Rewrite all strong electrolytes- soluble salts and strong acids/bases- in their fully disassociated ionic form.

Metalloprotein - Wikipedia

Metalloprotein is a generic term for a protein that contains a metal ion cofactor. A large proportion of all proteins are part of this egory. For instance, at least 1000 human proteins (out of ~20,000) contain zinc-binding protein domains although there may be up to 3000 human zinc metalloproteins. Abundance It is estimated that approximately half of all proteins contain a metal. In another
