Description:
Application
Sodium phosphate tribasic dodecahydrate (SP tribasic dodecahydrate) may be used to compose buffer solutions (pH in the range of 2 to 12) for use in a study. It may be used to prepare 500mM SP (sodium phosphate) buffer solutions for use in cloud point (CP) experiments.
General description
Sodium phosphate tribasic dodecahydrate is a hydrated trisodium salt of phosphoric acid. It is widely used in various water treatment methods.
