WebFinal answer Step 1/1 a) KNO2/HNO2 can be classified as a buffer system. This is because KNO2 is a salt of a weak base (HNO2) and a strong acid (HNO3), and HNO2 is a weak acid. The presence of a weak acid and its conjugate base in the solution makes it a buffer system. b) KHSO4/H2SO4 cannot be classified as a buffer system. Web1 Answer. Sorted by: 2.
