Provide definitions for the following terms: a. complex ion b. complex c. ligand d. monodentate ligand e. bidentate ligand f. coordination number g. calorimeter h. system (in this experiment) i. surroundings in this experiment)

Explanation:

Complex ion:

Complex ion is a coordinate compound with metal ion in its centre bonded to two or more ligand by coordinate bond. Transition metals ions are present in the centre.

Complex:

Transition metals bonded to two or more ligand by coordinate bond or dative bond are called metal complex or complex.

Monodentate ligand:

In metal complexes, ions or molecules bonded to central metal or metal ion through coordinate bond are called ligand.

Ligands bonded to central metal through only one atom are called monodentate legand.

Binodentate ligand:

Ligands bonded to central metal through only two atoms are called bidentate legand.

Coordination number:

In a coordination compound, the no. of atoms bonded to cental atom or central metal ion is known as coordination number.

Calorimeter:

Calorimeters are used for the determination of amount of heat released or absorbed in a chemical reaction.

System:

In thermodynamics, fixed quantity of matter around which a boundary can be drawn is called a system.

Surrounding:

Surroundings is a boundary around a system through which mass and energy are transferred.
