Compound 1 is soluble in water without decomposition. Treatment with NH 3 leads to the anion H 2NPF 5 . Upon heating 1 forms in good yield H 2NPF 4 and NH 4PF 6. Without a solvent 1 and NH 3 react to give (H 2N) 2PF 3. A mechanism for the ammonolysis of PF 5 is proposed...
The reversible splitting of H2 into protons and electrons is a key process in the metabolism of many prokaryotes and has been studied extensively in a wide range of bacteria and archaea. Environmental H2 is an energy source for aerobic H2 oxidizers, methanogens, acetogens, and sulfate reducers ...

Explain why tetrahydrofuran has a higher boiling point and is much more water soluble than furan, even though both compounds are cyclic ethers containing four carbons. What is the purpose of the boiling chips during simple distillation? How can the boiling point data for the possible compounds in...
It is also known as sodium dihydrogen phosphate or sodium phosphate monobasic. Monosodium phosphate is soluble in water and has a slightly acidic taste. It is commonly used as a pH regulator, emulsifier, and thickening agent in various food products. Additionally, it is used in the production ...
