Question 12.9b

Postby Anmol Dhaliwal 2C » Mon Nov 21, 2016 9:12 pm

For question 12.9b it asks which reactions can be classified as reactions between Bronsted acids and bases and to identify the acid and base for the ones that can. part b has the equation NH4I (s) ----> NH3 (g)+ HI (g) and in the solutions manual it lists NH4+ as the acid and I- as the base. Can someone please explain why this would be? Why is this possible if HI does not have a nitrogen in it but can still be the base and NH4 the acid? Thanks!

NH4I is the same as NH4+ and I-. Therefore, the NH4+ is the acid because it donates a proton to I- to form HI and I- is a base because it accepts the proton from NH4+. In the process, NH4+ becomes NH3 (ammonia). Hope this helps.
