Answer:
0.10M HCN < 0.10 M HClO < 0.10 M HNO₂ < 0.10 M HNO₃
Explanation:
We are comparing acids with the same concentration. So what we have to do first is to determine if we have any strong acid and for the rest ( weak acids ) compare them by their Ka´s ( look for them in reference tables ) since we know the larger the Ka, the more Hydronium concentration will be in these solutions at the same concentration.
HNO₃ is a strong acid and will have the largest hydronium concentration.
HCN Ka = 6.2 x 10⁻¹⁰
HNO₂ Ka = 4.0 x 10⁻⁴
HClO Ka = 3.0 x 10⁻⁸
The ranking from smallest to largest hydronium concentration will then be:
0.10M HCN < 0.10 M HClO < 0.10 M HNO₂ < 0.10 M HNO₃
Acids are substances that produce hydronium ions in solution.
According to Arrhenius definition, acids are substances that produce hydronium ions in solution. The concentration of these hydronium ions depends on the strength of the H-X bond.
The ease with which the H-X bond is broken to yield the proton is given by the Ka. The Ka is called the acid dissociation constant and shows the degree of ionization of an acid.
A strong acid has a high Ka hence it is completely dissociated in solution. A weak acid has a low Ka hence it dissociates only to a small extent in solution.
Given the equimolar solutions listed in the question, the order of hydronium ion concentration from smallest to largest is; HCN < HClO < HNO2< HNO3.
