FAQs
1. What is the color change observed during titration with Calmagite Indicator AR?
The indicator transitions from red in the presence of metal ions to blue at the titration endpoint when all metal ions are complexed.
2. Is Calmagite Indicator AR compatible with non-aqueous solvents?
It is primarily soluble in water and ethanol. For non-aqueous systems, pre-dissolution in a compatible solvent is recommended.
3. How should Calmagite Indicator AR be stored for long-term stability?
Store in a tightly sealed container, protected from light and moisture, at room temperature (15–25°C).
4. Can this indicator replace Eriochrome Black T in hardness testing?
Yes, Calmagite is often preferred for calcium and magnesium titrations due to its sharper endpoint and better stability in alkaline solutions.
5. What is the shelf life of Calmagite Indicator AR under ideal conditions?
When stored properly, the reagent remains stable for up to 24 months from the date of manufacture.
