Answer:

Cation is hydrogen ion or proton

Anion is chloride ion

Explanation:

Arrhenius theory:-

The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.

According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, [tex]H^+[/tex].

Thus, HCl dissociate as:-

[tex]HCl\rightarrow H^++Cl^-[/tex]

Thus, cation is hydrogen ion or proton

Anion is chloride ion

The ions in HCl are:

Cation: Hydrogen ion or proton

Anion: Chloride ion

According to Arrhenius theory:

It states that acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion.

Now, when HCl dissociates in water it produces two ions hydrogen ion and chloride ion.

[tex]HCl--->H^++Cl^-[/tex]

Thus, cation is hydrogen ion or proton and anion is chloride ion.
