Product Description:
Used as a visual pH indicator in laboratory settings, Alizarin red solution changes color depending on the acidity or alkalinity of a solution. It is particularly useful in titrations and pH testing where a clear color transition is needed. The solution typically shifts from yellow-orange in acidic conditions to purple or violet in alkaline environments, making it effective for detecting pH changes in the range of approximately 4.0 to 6.0. It is also employed in staining applications in biological and histological studies, where it helps visualize calcium deposits in tissues due to its affinity for calcium ions. Additionally, it serves in educational experiments to demonstrate acid-base reactions and pH scale concepts.
