Answer : The correct option is, H is the cation.
Explanation :
The general formula of an acid is represented as, [tex]HX[/tex] in which 'H' is hydrogen cation and 'X' is a non-metal or a poly-atomic anion.
For example : [tex]HCl, HNO_3, H_2SO_4[/tex] etc.
All the acids produces hydrogen ion, [tex]H^+[/tex] in an aqueous solution while the base produces hydroxide ion, [tex]OH^-[/tex] in an aqueous solution.
Hence, the correct answer is, H is the cation.
