Answer :
The table, which lists information about the measured acid dissociation constants of three unknown weak acids is 3,2 and 1 respectively.
Acid [tex]K_{a}[/tex] [tex]pK_{a}[/tex] Relative strength
A 1.6×10⁻¹¹ 10.8 3
B 1.64×10⁻² 1.78 2
C 2.5×10⁻² 1.6 1
Weak acids are acids that do not completely dissociate in solution. In other words, a weak acid is an acid that is not a strong acid. The strength of weak acids depends on the strength with which they dissociate. The more it dissociates, the stronger the acid. HCl is a strong acid because it dissociates almost completely.
KCl is naturally a salt with a strong basic cation and a strong acidic anion neither of which affect pH paper and has a standard value of pH 7.0 being neutral. shape. Vinegar is a combination of acetic acid and water made by a two-step fermentation process.
