WebHeating sodium tartrate dihydrate releases the two water molecules and changes the material to sodium tartrate (anhydrate). Sodium tartrate dihydrate’s melting point is 150℃. At room temperature, it is stable and does not release the water of crystallization in its molecules. When the temperature rises to 200℃, intermolecular bonds other than WebAbout 3 volumes of phosphate buffer with 0.2−0.3% 2-mercaptoethanol were added to the crushed leaves, blended for 2 min at low speed and then 3 min at the highest speed. ... reduced tartrate-resistant acid phosphatase-positive osteoclast number and …
