Phosphate minerals: Formula (repeating unit) Li 3 PO 4: IMA symbol: Lip [1] Strunz classification: ... Lithiophosphate is a natural form of (pure) lithium orthophosphate.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
The lithium, sodium, and potassium salts are prepared by reduction of chlorodiphenylphosphine, [1] triphenylphosphine, [2] [3] or tetraphenyldiphosphine with alkali metals (M): (C 6 H 5) 2 PCl + 2 M → (C 6 H 5) 2 PM + MCl (C 6 H 5) 3 P + 2 M → (C 6 H 5) 2 PM + MC 6 H 5 (C 6 H 5) 4 P 2 + 2 M → 2 (C 6 H 5) 2 PM. They can also be obtained by ...
Lithium finds use as a psychiatric medication and as an anode in lithium batteries. Sodium, potassium and possibly lithium are essential elements, having major biological roles as electrolytes, and although the other alkali metals are not essential, they also have various effects on the body, both beneficial and harmful.
Even with this proviso, the electrode potentials of lithium and sodium – and hence their positions in the electrochemical series – appear anomalous. The order of reactivity, as shown by the vigour of the reaction with water or the speed at which the metal surface tarnishes in air, appears to be Cs > K > Na > Li > alkaline earth metals,
Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl).
Sodium phosphide is the inorganic compound with the formula Na 3 P. It is a black solid. It is often described as Na + salt of the P 3− anion. [2] Na 3 P is a source of the highly reactive phosphide anion. It should not be confused with sodium phosphate, Na 3 PO 4.
Lithium phosphide is an inorganic compound of lithium and phosphorus with the chemical formula Li 3 P. This dark colored compound is formally the lithium salt of phosphine, consisting of lithium cations Li + and phosphide anions P 3−. It is hazardous to handle because of its high reactivity toward air. [1]
