The Cresol Red Analytical Grade by Dinâmica, available at LojaLab, is a sulfonephthalein acid-base indicator with two useful transition regions. The first typically occurs from pH 0.2 to 1.8, changing from red-orange to yellow. The second occurs from pH 7.0 to 8.8, changing from yellow to violet. This response supports titrations, pH monitoring and colorimetric systems covering strongly acidic media or conditions near neutrality and moderate alkalinity.
Characteristics
- Sulfonephthalein acid-base indicator also known as o-cresolsulfonephthalein
