WebPhosphine dissolves more readily in non-polar solvents than in water because of the non-polar P-H bonds. It acts as neither an acid nor a base in water. Proton exchange proceeds via a phosphonium (PH 4 + ) ion in acidic solutions and via PH 2 - at high pH, with equilibrium constants K b = 4 x 10 -28 and K z = 41.6 x 10 -29 .
