identify the correct acid and conjugate base pair in this equation: HNO2 + HS - --> NO2- + H2S
A. HNO2 is an acid and NO2- is the conjugate base.
B. HNO2 is an acid and H2S is the conjugate base.
C. HS- is an acid and NO2- is the conjugate base.
D. HS- is an acid and H2S is the conjugate base.
E. There is not an acid and conjugate base pair in the equation given.
Option (A) is correct.
An acid donates H+ and formed conjugate base.
So HNO2 is an acid and NO2- is conjugate base
