Question

Enter an equation showing how this buffer neutralizes added aqueous acid (HI). Express your answer as a chemical equation. Identify all of the phases in your answer.

Answer 1

the above answer is wrong

Step-by-step explanation:

its really not but the mastering chemistry says it is

Answer 2

`H^++NH_3\rightleftharpoons NH_4^+`

Step-by-step explanation:

Hello there!

In this case, since the buffer is not given, we assume it is based off ammonia, it means the ammonia-ammonium buffer, whereas the ammonia is the weak base and the ammonium ion stands for the conjugate acid. In such a way, when adding HI to the solution, the base of the buffer, NH3, reacts with the former to promote the following chemical reaction:

`H^++NH_3\rightleftharpoons NH_4^+`

Because the HI is totally ionized in solution so the iodide ion becomes an spectator one.
