Arancio metile

Descrizione:

Arancio metile è un colorante azoico comunemente usato come indicatore di pH nelle titolazioni, in particolare nell'intervallo acido. La sua formula chimica è C14H14N3NaO3S e appare come una polvere gialla o rossa, a seconda del pH della soluzione. Arancio metile mostra un cambiamento di colore distintivo da rosso a un pH inferiore a 3,1 a giallo a un pH superiore a 4,4, rendendolo utile per determinare il punto finale delle reazioni acido-base. È solubile in acqua e ha una tossicità relativamente bassa, anche se deve essere maneggiato con cura. Il composto è stabile in condizioni normali, ma può degradarsi se esposto a forti agenti ossidanti o a livelli estremi di pH. Arancio metile è utilizzato anche in varie applicazioni oltre all'indicazione del pH, inclusi i processi di tintura e come colorante biologico. Le sue proprietà uniche lo rendono uno strumento prezioso sia in laboratorio che in contesti industriali.

Methyl orange

CAS: 547-58-0

Methyl orange is a dye that is used as an indicator in acid-base titrations. It has a basic structure and can be prepared by the oxidation of para-aminobenzoic acid with hydrogen peroxide. Methyl orange has been shown to exhibit synergistic effects with other antimicrobial agents, such as phenol, methylene blue, and chlorhexidine at pH levels of 4.5 to 7.0. The optimum concentration for the matrix effect is 0.01% at pH range from 2.5 to 4.5 and 1% at pH range from 5 to 7.5. Methyl orange is activated by light with wavelengths between 300 nm and 500 nm and can be used in wastewater treatment processes where there are high levels of organic matter or radiation, such as carthamus tinctorius or zirconium oxide.
