The indicator works by changing color based on the hydrogen ion concentration in your solution. Below pH 6.4, it appears yellow, while above pH 8.2, it turns a bright pink or fuchsia. In the intermediate range (6.4-8.2), you’ll observe various shades of red, providing visual confirmation of your solution’s pH.
This particular phenol red indicator comes in a convenient 5g pack size, offering enough quantity for multiple experiments while maintaining freshness. The ACS grade certification means it meets the strict purity standards set by the American Chemical Society, ensuring interference-free results in your analyses.
When preparing your phenol red solution, typical concentrations range from 0.01% to 0.1% depending on your specific application. For most laboratory uses, a 0.04% solution (40mg per 100ml) provides excellent visibility of color changes.
