What is Disodium Phosphate Dodecahydrate?

Disodium Phosphate Dodecahydrate is an inorganic compound with the formula Na₂HPO₄·12H₂O. It is the hydrated form of disodium hydrogen phosphate and appears as a white crystalline solid. It is widely used in laboratories, food processing, and industrial applications.

What are the uses of disodium phosphate dodecahydrate?

Common uses of Disodium Phosphate Dodecahydrate include its role as a buffering agent, emulsifier, and pH regulator. It is used in food additives, detergents, water treatment, pharmaceuticals, and analytical chemistry.

What is disodium phosphate dodecahydrate used for in laboratories?

In labs, it's often used as a reagent in buffer solutions, particularly in biochemical and pharmaceutical research, to maintain stable pH levels during experiments.

What is the melting point of disodium phosphate dodecahydrate?

The melting point of Disodium Phosphate Dodecahydrate is approximately 35–37°C (95–98.6°F). At this temperature, the compound begins to lose its water of hydration and transition into an anhydrous or lower hydrate form.

What is the boiling point of disodium phosphate dodecahydrate?

The boiling point of Disodium Phosphate Dodecahydrate is not well-defined because the compound decomposes upon heating, losing its hydration water before it reaches a true boiling point. It is not typically boiled in standard procedures.
