Chemical name of common white pigment used in paint is :
Answer: A
The common white pigment is titanium dioxide, \(TiO_{2}\).
Titanium dioxide, mainly in its rutile form, is the most important white pigment in paint because of its very high refractive index, which gives excellent opacity and brightness. It largely replaced the older lead white and zinc white. In forensic paint analysis it is one of the inorganic components identified by techniques such as SEM-EDX or XRF.
Aluminium oxide is used as an abrasive and filler, tin oxide as an opacifier in ceramic glazes, and cadmium sulphide is a yellow pigment (cadmium yellow), not a white one.
