Hydrides react spontaneously and irreversibly with proton donors, including water and acids, to form flammable H2 gas (Rittmeyer, P., U. Wietelmann. 2002. Hydrides. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online); Eggeman, T. 2001. Hydrides. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).
Phosphoric acid and sodium tetrahydroborate may react violently (Gard, D. R. and Updated by Staff 2005. Phosphoric Acids and Phosphates. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).
Phosphonic and phosphinic acids can be reduced to phosphines with lithium aluminum hydride (Fee, D. C., Gard, D. R. and Yang, C.-H. 2006. Phosphorus Compounds. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).
Sodium hydride performs addition reactions with Lewis acids (Sullivan, E. and Wade, R. 1980. Hydrides. Kirk-Othmer Encyclopedia of Chemical Technology, 3rd ed. John Wiley & Sons, Inc.).
