What will be the conjugate bases for the following Bronsted acids : HF, H_2SO_4 and HCO_3?

Answer»

Solution :Conjugate base = ACID - `H^+`
The conjugate bases should have one proton and +1 charge LESS than acid.
Conjugate base ofHF=`(HF-H^+)=F^-`
Conjugate base of `H_2SO_4 = (H_2SO_4-H^+) =HSO_4^-`
Conjugate base of `HCO_3^(-) = (HCO_3^(-)- H)=CO_3^(2-)`
