Lithium fluoride boiling point
The boiling point of lithium fluoride is 1676 degree Celsius or 1949 Kelvin. According to fahrenheit scale it is 3049 degree fahrenheit.
Lithium fluoride state at room temperature
Lithium fluoride is found to be a white coloured powder or a transparent crystal which is hygroscopic in nature.
Lithium floride ionic bond
Lithium fluoride is made by the ionic bond between lithium ion and fluoride ion. Lithium lost one of its electron to become Li+ and fluorine accepts that electron to become F– . Then they attract each other to form the compound.
Lithium fluoride ionic radius
The ionic radius of lithium fluoride is 1.570.
Lithium fluoride electron configuration
The various orbitals involved in filling electrons are s,p,d and f. Let us discuss about the electronic configuration of LiF.
The electronic configuration of lithium is 1s1 2s1 and Fluorine is 1s1 2s2 2p3.
Lithium fluoride oxidation State
The oxidation state of lithium fluoride is zero.
Lithium fluoride acidity or alkaline
The aqueous solution of lithium fluoride is found to be acidic.
Is Lithium fluoride odourless?
Lithium fluoride is an odourless solid substance with a bitter or saline like taste.
Is Lithium fluoride paramagnetic?
Paramagnetic substance have a permanent dipole moment. Let us check whether Lithium fluoride is paramagnetic or not.
Lithium floride is found to be a diamagnetic substance because all the electrons are paired.
Lithium fluoride hydrates
Lithium fluoride doesn’t form in a type of hydrate as it does not react with oxides.
Lithium fluoride crystal structure
The crystal structure of lithium fluoride a face-centred cubic lattice with the lattice constant value of 403.51 Pico metre.
Lithium fluoride polarity and conductivity
Lithium fluoride is a polar compound with a dipole moment value 6.327 D. It is Polar in nature because of it’s ionic character. Lithium fluoride has 83.9% ionic character. Also the compound is formed by the electrostatic attraction of two opposite charge is the reason for its ionic behaviour.
Lithium fluoride is found be good conductor because it is an ionic compound. Most of the ionic compounds are found to be good in conductivity.
Lithium fluoride reaction with acid
Lithium fluoride react with hydrogen fluoro acid to form Lithium hydrogen fluoride and also with hydrogen chloride to form lithium chloride and hydrogen fluoride.
LiF + HCl → LiCl + HF
LiF + HF → LiHF2
Lithium fluoride reaction with base
Lithium fluoride react with a base like Lithium hydroxide to form a double salt with the formula LiF. LiOH.
LiF + Li(OH)2 → LiF.Li(OH)2
Lithium fluoride reaction with oxide
There is no reaction observed for Lithium fluoride and oxides because of its shielding structure.
Lithium fluoride react with a metal
There is no reaction found in between Lithium fluoride and metal because of Oxygen vacancies.
Conclusion
Lithium chloride is used in Lithium Phosphorus hexa fluoride batteries, electrolysis of fluorine, in vaccum ultraviolet spectrum, radiation detectors and nuclear reactors. When heated Lithium fluoride forms toxic fluoride gas.
