Question

which of the following have bronsted acid? (a)HSO3- (b)HCO3- (c) both a and b (d) none

Answer 1

None 
 Here is your correct answer 
       Let's now look at the reaction between ammonia (NH3) andhydrochloric acid (HCl). If we identify each substance, thenNH3 is the Bronsted-Lowry base, HCl is the Bronsted-Lowry acid, NH4+ is the conjugate acid and Cl- is theconjugate base. The conjugate acid-base pairs are:HCl/Cl- and NH3/NH4+
