Question

Given the equation representing a reaction: H2CO3 + NH3 → NH4+ + HCO3– According to one acid-base theory, the compound NH3 acts as a base because it

1. accepts a hydrogen ion
2.donates a hydrogen ion
3.accepts a hydroxide ion
4.donates a hydroxide ion

Answer 1

answer is 1. this is what bases do, they take (accept) hydrogen ions. 

Answer 2

Answer: The correct answer is Option 1.

Step-by-step explanation:

According to Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates hydrogen ion and base is defined as a substance which accepts hydrogen ion.

In the given equation:

`H_2CO_3+NH_3\rightarrow NH4^++HCO_3^-`

`NH_3` is accepting a hydrogen ion and is forming
`NH_4^+`, therefore it is considered as a base.

`H_2CO_3` is donating a hydrogen ion and is forming
`HCO_3^-`, therefore it is considered as an acid.

Hence, the correct answer is Option 1.
