Product Description:Thymolphthalein complexone is a offwhite powder that is dissolved into a clear, colorless liquid when added to isopropyl alcohol. A metal indicator, it turns a brilliant blue-magenta color when it comes in contact with basic solutions like sodium hydroxide or ammonia hydroxide, and returns to clear when an acid is introduced to the solution, balancing out the pH.
Applications:The reagent will form colored metal complexes in alkali media. It is used for determination of Calcium and MagnesiumIt is a Complexometry indicator, for determination of Ca, Sr and Ba. Acidic form retains hydrogen on each hydroxyl group.

Product Description:

Bromophenol blue is an acid-base indicator since its useful range lies between pH 3.0 and 4.6. It changes from yellow at pH 3.0 to blue at pH 4.6; this reaction is reversible. Bromophenol blue is structurally related to phenolphthalein (a popular indicator). Bromophenol blue is also used as a color marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis
