view more201611 · The term cyanide generally refers to one of three classifications of cyanide, and it is critical to define the class of cyanide that is to be treated. The three classes of cyanide are: (1) total cyanide, (2) WAD cyanide, and (3) free cyanide, as shown in Figure 35.1.Each of these forms of cyanide has specific analytical methodologies for its …
view moreLigand Exchange Reactions (Introduction) This page describes some common ligand exchange (substitution) reactions involving complex metal ions. It assumes that you are familiar with basic ideas about complex ions. A ligand exchange reaction involves the substitution of one or more ligands in a complex ion with one or more different ligands.
view moreIn the given reaction, zinc reacts with silver nitrate to form Zinc nitrate and silver. The chemical reaction can be represented as: Zn (s) Zinc + AgNO 3 (aq) Silver nitrate → Zn (NO 3) 2 (aq) Zinc nitrate + Ag (s) Silver. Balancing the Chemical Equation: Step 1: Write the number of atoms of each element. Zn (s) Zinc + AgNO 3 (aq) Silver ...
view moreThis demonstration operates on the following reaction: Fe 3+ aq + SCN-aq ↔ FeSCN 2+ aq . The local additions of either ferric ions or thiocyanate ions will each provide local color intensities by shifting the equilibrium. Iron nitrate shifts the above equation to the right, and so too does potassium thiocyanate.
