transition metals and reaction of aq ions

the process of forming weak bonds by reactants to the surface of a solid catalyst

a reaction where the product of a reaction acts as a catalyst for the reaction

ligand that can form two co-ordinate bonds

used in colorimetry to plot the amount of absorbance vs concentrations of standard solutions. This is then used to measure the concentration of an unknown solution of your transition metal ion

Impurities in a reaction mixture may bind to a heterogeneous catalyst’s surface and block reactants from being adsorbed.

the process by which a multidentate ligand replaces a monodentate ligand in forming co-ordinate (dative) bonds to a transition metal ion

A type of stereoisomerism. Octahedral complexes with four monodentate ligands of one type and two monodentate ligands of another type can show cis-trans isomerism. If the two odd ligands are opposite, it is the trans isomer. If the two odd ligands are next to each other, it is the cis isomer

A transition metal compound which is used as an anti cancer drug. It has a square planar shape

Instrument used in spectroscopy which calculates how much light is absorbed by the sample

A central metal atom or ion surrounded by coordinately bonded ligands

An industrial process used to produce sulfuric acid. Vanadium(V) oxide acts as a heterogeneous catalyst

is a covalent bond in which both electrons in the shared pair come from the same atom

The number of coordinate bonds that are formed with the central metal ion

A catalyst that is in a different phase from the reactants

Catalysts that are in the same phase as the reactants - i.e. in the same physical state

an atom, ion or molecule that forms a co-ordinate (dative) bond with a transition metal ion using a lone pair of electrons

A reaction in which a ligand is substituted by another ligand

Ligands that can only form one co-ordinate bond

Ligands that can form more than one co-ordinate bond

type of stereoisomerism which occurs when a substance exists in two forms that are non-superimposable mirror images. Complex ions can show optical isomerism when a central metal ion is coordinately bonded to three bidentate ligands

A titration experiment to determine the concentration of an unknown solution by carrying out a redox reaction between the two reactants

A technique used to determine the concentration of a solution by measuring how much light it absorbs

A metal that can form one of more stable ions with a partially filled d sub-level

Transition elements have variable oxidation states which means they can form ions with different oxidation states
