Tulajdonságok és Használat:
1. pH indicator
Methyl orange is red in an acidic environment and yellow in a weakly alkaline environment. This property makes it an ideal indicator in strong acid-weak base titration, which can help quickly and accurately determine the pH value of the solution.
2. Chemical analysis and titration
As a reliable acid-base indicator, the bright color change of methyl orange can clearly mark the titration endpoint. It is used to analyze the reaction between strong acids such as sulfuric acid and hydrochloric acid and alkaline substances to ensure the accuracy of experimental results.
3. Environmental monitoring and water quality analysis
In the field of water quality monitoring, methyl orange is used to monitor the quality of industrial wastewater and river water by detecting pH changes, and to help determine the degree of pollution.
4. Pharmaceutical research and laboratory reagents
Methyl orange is often used for reaction observation and solubility testing in drug development due to its stable chemical properties and simple operation.
Tárolási feltételek: It should be sealed and shaded to be stored in a dry, cool, well ventilated place.
