Buffer |
A solution that opposes the change in ph when an acid or alkali is added to the solution. |
|
|
Convert [H+] to pH |
pH = -log10([H+]) [H+] = 10^-(pH) |
|
|
Monodentate ligand |
A species that has one lone pair of electrons with which it can form a coordinate (dative covalent) bond with a central metal atom/ion. |
|
|
Bidentate ligand |
A species that has two lone pairs of electrons with which it can form a coordinate (dative covalent) bond with a central metal atom/ion. |
|
|
Transition metal |
A metal that forms at least one stable ion with a partially filled d subshell. Zinc forms Zn2+ so has a configuration of 3s2 3p6 3d10. Full d subshell so isn't a transition metal. Scandium forms Sc3+ with configuration 3s2 3p6. No electrons in the d orbitals so not a transition metal.

Electron configuration of Cr and Cu |
Cu: [Ar] 3d10 4s1 Cr: [Ar] 3d5 4s1 Usually 4s orbital fills before 3d10 but in these cases the d subshell takes the extra electron and not the 4s orbital. |
