Frozen HCl undergoes a phase transition at 98.4 K (−174.8 °C; −282.5 °F). X-ray powder diffraction of the frozen material shows that the material changes from an orthorhombic structure to a cubic one during this transition. In both structures the chlorine atoms are in a face-centered array.
nh 3 + 3 c 2 h 5 oh → n(c 2 h 5) 3 + 3 h 2 o The pK a of protonated triethylamine is 10.75, [ 4 ] and it can be used to prepare buffer solutions at that pH. The hydrochloride salt , triethylamine hydrochloride (triethylammonium chloride), is a colorless, odorless, and hygroscopic powder, which decomposes when heated to 261 °C.
The official SI symbols are g/cm 3, g·cm −3, or g cm −3. It is equivalent to the units gram per millilitre (g/mL) and kilogram per litre (kg/L). The density of water is about 1 g/cm 3, since the gram was originally defined as the mass of one cubic centimetre of water at its maximum density at 4 °C (39 °F). [1]
6 PCl 5 + P 4 O 10 → 10 POCl 3. The reaction can be simplified by chlorinating a mixture of PCl 3 and P 4 O 10, generating the PCl 5 in situ. The reaction of phosphorus pentachloride with boric acid or oxalic acid: [12] 3 PCl 5 + 2 B(OH) 3 → 3 POCl 3 + B 2 O 3 + 6 HCl PCl 5 + 2 → POCl 3 + CO + CO 2 + 2 HCl
