The oxidation number of an atom or ion in a molecule or ion is determined by first finding the sum of the oxidation numbers of other atoms or ions that are attached to it and then equate the sum to the total charge on the ion or molecule.Answer and Explanation: The oxalate ion is: ...
Is bidentate a ligand? Bidentate ligands have two donor atoms which allow them to bind to a central metal atom or ion at two points. Common examples of bidentate ligands are ethylenediamine (en), and the oxalate ion (ox). Is carbon monoxide a bidentate ligand? The ligands are defined as ...
Calculate the concentration of oxalate ion (C_2O_4^{2-}) in a 0.175 M solution of oxalic acid (C_2H_2O_4). (For oxalic acid, Ka1 = 6.5 x 10^{-2}, Ka2 = 6.1 x 10^{-5}) An oxalic acid, H_2C_2O_4, solution of unknown concentration is standardized against 0.110...
What are Oxalates? Oxalate can be described as an anion having the chemical formula C2O42-. It is a dianion because it is a combination of two charged species that we can write as (COO)22-. We can abbreviate this ion as “ox.” Furthermore, it can occur as an anion in ionic co...

What is hydrometallurgical refining?Hydrometallurgical processes allow to obtain as final products base metals (Cu, Zn) and salts of critical metals like yttrium and europium oxalates with high purity that could be sent to the market or sold to companies for refining....
A molecular formula describes which atoms are present in a molecule. The subscript number found after the elemental symbol indicates the number of atoms present for each element in the molecule. Answer and Explanation: The molecular formula of ammonium nitrate is NH4NO3. The molecular formula indicat...
