FAQ
What is Methyl Red Sodium Salt (C.I. 13020) technical grade used for?
Methyl Red Sodium Salt (C.I. 13020) technical grade is commonly used as a pH indicator in various laboratory applications. It changes color depending on the acidity of a solution, making it a valuable tool in titrations and other chemical analyses.
How does Methyl Red Sodium Salt work as a pH indicator?
Methyl Red Sodium Salt works by changing color in response to changes in the pH of a solution. In acidic conditions, it appears red, while in alkaline conditions, it turns yellow. This color change is due to the protonation or deprotonation of the indicator molecule, resulting in different absorption spectra.
What are some other applications of Methyl Red Sodium Salt (C.I. 13020) technical grade?
In addition to its use as a pH indicator, Methyl Red Sodium Salt technical grade is also utilized in microbiology to differentiate between bacteria that produce mixed-acid fermentation products. It is also used in the textile industry as a dye.
How should Methyl Red Sodium Salt (C.I. 13020) technical grade be stored?
Methyl Red Sodium Salt should be stored in a cool, dry place away from direct sunlight and moisture. It is important to keep the container tightly closed when not in use to prevent contamination and degradation of the product.
Are there any safety precautions to consider when handling Methyl Red Sodium Salt (C.I. 13020) technical grade?
It is important to wear appropriate personal protective equipment, such as gloves and goggles, when handling Methyl Red Sodium Salt. Avoid inhaling the powder or getting it in contact with skin or eyes. In case of contact, rinse thoroughly with water and seek medical attention if necessary.
