Why do $HCl$, $HNO_3$, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character ?
The dissociation of $HCl$ or $HNO_3$ to form hydrogen ions always occurs in the presence of water. Hydrogen ions $(H^+)$ combine with $H_2O$ to form hydronium ions $(H_3O^+)$.
The reaction is as follows :
$HC{{l}_{(aq)}}\,\to {{H}^{+}}\,+\,C{{l}^{-}}$
${{H}^{+}}\,+\,{{H}_{2}}O\,\to {{H}_{3}}{{O}^{+}}$
Although aqueous solutions of glucose and alcohol contain hydrogen, these cannot dissociate in water to form hydrogen ions. Hence, they do not show acidic character.
How is the concentration of hydroxide ions $(OH^-)$ affected when excess base is dissolved in a solution of sodium hydroxide ?
You have two solutions, $A$ and $B$. The $pH$ of solution $A$ is $6$ and $pH$ of solution $B$ is $8$. Which solution has more hydrogen ion concentration Which of this is acidic and which one is basic?
Why do acids not show acidic behaviour in the absence of water ?
