$a) H_{2} O$
$H_{2} O \Rightarrow H^{+} + O H^{t}$
$H_{2} O$ can be both an Arrhenius acid and base. It`s self-ionization both H^+ and OH^- ions.
$b) C a {(O H)}_{2}$
$C a (O H)_{2} \Rightarrow C a^{2} + 2 O H^{t}$
$C a {(O H)}_{2}$ is not an Arrhenius acid. It is n Arrahenius bases since it produced $O H^{-} i o n$ .
$c) H_{3} P O_{4}$
$H_{3} P O_{4} \Rightarrow H_{3} P O_{4}^{-} + H^{+}$
$H_{3} P O_{4}$ is an Arrahenius acid because it produced $H^{+}$ ion.
$d) H I$
$H I \Rightarrow H^{+} + I^{t}$
$H I$ is an Arrhenius acid because it produced $H^{+}$ ion.
We get result where $a) H_{2} O, c) H_{3} P O_{4}, 4) H I$ are Arrhenius acids.
