{eq}NH4^+(aq) + H2O (l) → NH3(aq) + H3O^+(aq) {/eq} Bronsted-Lowry Acid-Base Reaction: Covalent "H-X" bonds are the basis of the Bronsted-Lowry theory of acids and bases. One or more of these bonds are dissociated to an appreciable degree ...
The Cauchy pressures and B/G values indicate that NH4ClO4 exhibits ductility, attributed to the fact that NH4ClO4 is an ionic crystal, and ionic bonds are non-directional bonds;hence, NH4ClO4 is ductile and can be easily bended or reshaped. The results indicate that the ductility properties...

The hydrogen bonds in both structures are so-called charge-assisted; that is, the H-bond donor and/or acceptor carry positive and/or negative ionic charges, respectively. The H-bonded network in 1 consists of one formally mono-deprotonated 4-phosphonato-biphenyl-41-carboxylic acid group; that...
Carboxylato complexes exhibiting ∆ values that are significantly greater than ionic values, typically with ∆ ≥ 200 cm−1 (cf. 164 and 184 cm−1 for zwitterionic β-HAla [53]), have usually unidentate coordination [54]. The ∆ values of studied compounds (∆ = 230 for 1, 2...
