Question

Which pair of compounds represents one Arrhenius acid and one Arrhenius base?

(1) CH3OH and NaOH (3) HNO3 and NaOH

(2) CH3OH and HCl (4) HNO3 and HCl

Answer 1

HNO3 AND NaOH

Step-by-step explanation:

Arrhenius acids have H as the only plus ion solution and Arrhenius base contains OH negative is the only negative ions in aqueous solution

Answer 2

Answer: 3)
`HNO_3` and
`NaOH`

Step-by-step explanation:

According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion.

`HNO_3\rightarrow H^++NO_3^-`

According to the Arrhenius concept, a base is a substance that ionizes in the water to give hydroxide ion.

`NaOH\rightarrow Na^++OH^-`

Thus
`HNO_3` is an arrhenius acid and
`NaOH` is an arrhenius base.
