🏭⚗️ Synthesis
mixed pH indicator for pH 4.5 is made by dissolving specific amounts of indicators (e.g., methyl red and bromocresol green) in methanol. Example: dissolve 0.1 g methyl red and 0.05 g bromocresol green in 100 mL methanol. Store in a dark, tightly sealed container.
🧪 Applications
Used in acid-base titrations where a clear color change around pH 4.5 is needed. Especially useful in non-aqueous titrations, pharmaceutical analysis, and laboratory quality control.
⚠️ Safety
Contains methanol, which is toxic and flammable. Dyes may irritate skin or eyes. Use gloves, goggles, and work in a ventilated area. Store safely and dispose of properly.
