justify nh4+is conjugated acid of hco3-
Which of the following could not be a Bronsted acid? O2- HCO3- HS- HCl NH4+
Calculate the value for the equilibrium constant of this reaction: NH4+(aq)+HCO3-(aq)↔NH3(aq)+H2CO3(aq) where [NH4+]=0.25 M, [HCO3-]=0.42 M, [NH3]=0.0078 M, and [H2CO3]=0.018 M. answer= 1.3 *10^-3
Acids and bases: definitions Consider the following reactions: (a) NH4+ + CO32- → NH3 + HCO3 (b) 2 HBr + Ca(OH)2 → CaBr2 + 2 H2O (C) SO3 + H2O → H2SO4 Match with the definitions that apply for the substances indicated. Note: In a given reaction, the same definition must apply for both the acid and base for it to hold true. NH4+ Choose... CO32- Choose... HBr Choose... Ca(OH)2 Choose... Choose... SO3 H2O in (c) Choose...
