Answer
a. It is a weak acid. So, the concentration of $H_{3}O$+ is less than HClO2. Therefore [$H_{3}O$+] <1.25M.
b. $H_{3}PO_{4}$ is a strong acid and concentration of $H_{3}O$+ is the same as $H_{3}PO_{4}$. Therefore [$H_{3}O$+]= 1.25 M.
c. HCl is a strong acid and concentration of $H_{3}O$+ is the same as HN
d. It is a weak acid. So, the concentration of $H_{3}O$+ is lower. Therefore [$H_{3}O$+] < 0.95M.

a. It is a weak acid. So, the concentration of $H_{3}O$+ is less than HClO2. Therefore [$H_{3}O$+] <1.25M.
b. $H_{3}PO_{4}$ is a strong acid and concentration of $H_{3}O$+ is the same as $H_{3}PO_{4}$. Therefore [$H_{3}O$+]= 1.25 M.
c. HCl is a strong acid and concentration of $H_{3}O$+ is the same as HN
d. It is a weak acid. So, the concentration of $H_{3}O$+ is lower. Therefore [$H_{3}O$+] < 0.95M.
