is a weak acid, but its strength increases with concentration has to be explained
Weak acids ionize only to limited extent in water. At equilibrium, an aqueous solution of a weak acid has a mixture of unionized acid molecules, hydronium ions and corresponding conjugate base.
Le Chatelier’s Principle:
This principle states that “at equilibrium, when any system is subjected to change in temperature, volume, pressure or concentration, then the system adjusts itself to counteract the effect of the applied change by establishing a new equilibrium”
To Explain: is a weak acid, but its strength increases with concentration.
