$\mathrm{P}{\mathrm{H}}_4^{+}$ion is tetrahedral like the$\mathrm{N}{\mathrm{H}}_4^{+}$ion and is obtained when$\mathrm{P}{\mathrm{H}}_3$is bonded to proton

$\mathrm{P}{\mathrm{H}}_4\mathrm{I}$is one of the most stable salts containing the phosphonium ion. It is also more stable than ammonium salts

$\mathrm{P}{\mathrm{H}}_4\mathrm{I}$is decomposed by water to form$\mathrm{P}{\mathrm{H}}_3$

$\mathrm{P}{\mathrm{H}}_3$converts silver salts in solution to silver phosphide, which subsequently reacts to give free metal
