Identify and label the brønsted-lowry acid, its conjugate base, the brønsted-lowry base, and its conjugate acid in each of the following equations:

(a) hno3+h2o⟶h3o++no3−
(b) cn− +h2o ⟶ hcn+oh−
(c) h2so4+cl− ⟶hcl+hso4−
(d) hso4−+oh− ⟶so42−+h2o
(e) o2− + h2 o ⟶ 2oh−

Explanation:

As per Brønsted-Lowry concept of acids and bases, chemical species which donate proton are called Brønsted-Lowry acids.

The chemical species which accept proton are called Brønsted-Lowry base.
