WebThe structure and color of crystal violet depend on pH, making it a valuable acid-base indicator as well as an excellent dye. Crystal violet absorbs electromagnetic radiation (light) in the ultraviolet and visible light range with an optimal absorbance around 590nm. WebThere are basic classes of crystal defects: point defects, which are places where an atom is missing or irregularly placed in the lattice structure. Point defects include lattice vacancies, self-interstitial atoms, substitution impurity atoms, and interstitial impurity atoms. linear defects, which are groups of atoms in irregular positions.
