Reagecon's Chemical Indicators
It is important to select the appropriate indicator according to the pH range or redox properties required for the specific analysis in your laboratory.
Below is a list of Reagecon's chemical indicators currently available on our CymitQuimica website, including both Acid-Base and Redox indicators.
Acid-Base Indicators
Acid-base indicators are organic compounds that act as weak acids or bases, and have a weaker acidic or basic character than the compounds involved in the titration. These indicators exhibit a different colour in their acidic form compared to their basic form.
The high-quality acid-base indicator solutions from Reageconare manufactured using superior raw materials and are rigorously tested. They provide clear and precise colour changes for accurate detection of the endpoint in manual titrations, ensuring reliable results.
1. Phenolphthalein: It is an indicator that changes from colourless to red in the pH range of 8.0 to 10.0.
- Phenolphthalein Indicator Solution 0.1%
- Phenolphthalein Indicator Solution 0.2%
- Phenolphthalein Indicator Solution 0.5%
2. Bromocresol Green: Changes from yellow to blue in the pH range of 3.8 to 5.9.
3. Crystal Violet: Its solutions are deep violet in colour.
4. Bromophenol Blue: Changes from yellow to blue in the pH range of 3.0 to 4.6.
5. Phenol Red: Changes from yellow to red in the pH range of 6.8 to 8.2.
- Phenol Red Indicator Solution according to the European Pharmacopoeia (EP)
- Phenol Red Indicator Solution 0.5% (w/w)
6. Methyl Orange: Changes from pink to yellow in the pH range of 3.1 to 4.4.
A redox indicator is an organic substance that exhibits a different colour in its oxidised form compared to its reduced form. Like acid-base indicators, redox indicators function similarly, but instead of responding to pH, they react to the redox potential of the system.
1. Methylene Blue: Used in redox titrations, it changes from blue to colourless when reduced.
2. Potassium Dichromate: Acts as an indicator in certain redox reactions, changing from orange to green when reduced.
- Potassium Dichromate Solution according to the European Pharmacopoeia (EP): This is a stable, high-purity product developed and tested for European Pharmacopoeia (EP) applications. These include use in identification reactions for ions and functional groups and its use as a reagent in performing tests described in various EP monographs.
- Potassium Dichromate 0.01667M Solution according to the Chinese Pharmacopoeia (ChP): This analytical volumetric solution from Reagecon is accurate, stable, reproducible, and fully factorised.
