Acid chrome blue K is a chromogenic dye featuring a sulfonated azo structure with enhanced water solubility and thermal stability. This compound serves as a sensitive indicator in metal ion titrations, particularly for calcium and magnesium, due to its distinct color transition upon complexation. The para-sulfonate substitution improves solubility and reduces aggregation, enabling reliable performance in aqueous analytical workflows.
Acid chrome blue K serves as a reliable chromogenic indicator in complexometric titrations, particularly for the determination of calcium and magnesium ions. Its distinct color change from blue to red at the endpoint ensures clear visual detection. The compound exhibits good stability under standard laboratory conditions and demonstrates consistent performance in aqueous solutions across typical titration pH ranges.
