4 days ago · The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
Jul 11, 2024 · Ultraviolet–visible (UV-vis) spectroscopy. DIscover how unsaturation in organic compounds leads to colour. Such electon configuration allows transitions between orbitals of lower energy and antibonding orbitals occur when electromagnetic radiation of suitable energy is absorbed by the molecule.
An acid-base indicator is either a weak acid or weak base that exhibits a color change as the concentration of hydrogen (H +) or hydroxide (OH -) ions changes in an aqueous solution. Acid-base indicators are most often used in a titration to identify the endpoint of an acid-base reaction.
Jul 5, 2024 · Hint: As we know that a chemical change cannot always be visible to the naked eye but sometimes it occurs to change the colour of chemicals or solution when a chemical change takes place. So here we have to give an example of change in the substance’s colour during a reaction.
2 days ago · Titanium dioxide, also known as titanium (IV) oxide or titania / taɪˈteɪniə /, is the inorganic compound derived from titanium with the chemical formula TiO. 2. When used as a pigment, it is called titanium white, Pigment White 6 ( PW6 ), or CI 77891. [4]
Jul 10, 2024 · The electron configuration of transition metal complexes is essential in understanding their behaviour. Understand the theory of how d-orbitals influence colour through their shape and crystal field splitting.

3 days ago · Chemical reactions happen at a characteristic reaction rate at a given temperature and chemical concentration. Some reactions produce heat and are called exothermic reactions, while others may require heat to enable the reaction to occur, which are called endothermic reactions.
