Which two formulas represent arrhenius acids?
(1) ch3cooh and ch3ch2oh
(2) hc2h3o2 and h3po4
(3) khco3 and khso4
(4) nascn and na2s2o3

Answer : The correct option is, (2)

Explanation :

Arrhenius theory : It sates that an acid is a type of substance that ionizes in the water to give the hydronium ion or hydrogen ion and a bases is a type of substance that ionizes in the water to give hydroxide ion .

Or we can say that,

Arrhenius acid are those which can easily gives the hydrogen ion in a solution and Arrhenius base are those which can easily gives the hydroxide ion in a solution.

In option 1, can easily gives the hydrogen ion but can not gives the hydrogen ion due to stronger O-H bonding. So, these formulas does not represent Arrhenius acids.

In option 2, and can easily gives the hydrogen ion. So, these formulas represent Arrhenius acids.

In option 3, and can not gives the hydrogen ion because both are the salts. So, these formulas does not represent Arrhenius acids.

In option 4, and can not gives the hydrogen ion because no hydrogen present in the compound. So, these formulas does not represent Arrhenius acids.

Hence, (2) represent Arrhenius acids.
