Product Introduction
Titration is a quantitative analysis method that determines the content of a solute by quantitatively reacting two solutions. In the online detection instrument for methyl orange acidity, titration method is used to measure the acidity of methyl orange in water samples. It relies on the chemical reaction between two solutions and the color change of the indicator to determine the titration endpoint. Methyl orange, as an indicator, can sensitively reflect changes in the concentration of hydrogen ions in a solution through color changes. At the endpoint of titration, the color of methyl orange will change, indicating that the reaction has reached the predetermined acidity value. During the titration process, a standard alkaline solution of known concentration (such as sodium hydroxide solution) is slowly added dropwise to the water sample to be tested. With the addition of alkaline solution, the hydrogen ions in the water sample are neutralized, and the color of methyl orange gradually changes. When the color of methyl orange changes from yellow to orange (or from red to yellow, depending on the specific pH range and the color change point of methyl orange), it is considered that titration has reached the endpoint. At this point, the volume of standard alkali solution consumed can be used to calculate the acidity of methyl orange in the water sample.
