Why does a strong acid have a weak conjugate base, whereas a weak acid has a relatively strong conjugate base? Explain. Explain. The expression for the base constant is derived by following the usual rules for writing an equilibrium constant for a chemical reaction, with the additional feature that the concentration of water is dropped from the . Let us first write the equation of dissociation C 6 H 5 N H 3 + ( a q) + H 2 O ( l) C 6 H 5 N H 2 ( a q) + H 3 O + ( a q). Hydrobromic acid. Hence, Methanol is a weaker acid than water. It could contain either an excess of hydronium ions or an excess of hydroxide ions because the nature of the salt formed determines whether the solution is acidic, neutral, or basic. CH3CH2NH3+ Weak acid. Es ridculo que t ______ (tener) un resfriado en verano. Me molesta que mis padres no ______ (cuidar) su alimentacin.. 3.
