Acid Base Identification

Postby Isabel Nakoud 4D » Mon Dec 03, 2018 8:31 pm

Homework problem 12. 9 state that in the formula

NH4I --> NH3 + HI

NH4+ is the Bronsted acid and that I- is the Bronsted base. How is this possible, that the acid and base is the same compound?

Can someone please explain/walk me through this problem?

The molecule NH4I dissociates into 2 species NH4+ and I- . Bronsted acids donate protons (H+) and bronsted bases accept protons (H+). I- + H+ --> HI means that I accepts that proton and acts as a base. NH4+ --> NH3 + H+ means that the ammonium ion donates the H+ and is an acid.
