Identify the products formed in this Brønsted-Lowry reaction. HCO−3+NO−2↽−−⇀acid+base

Question

I get confused with these type of problems. What would the base and acid be?

Answer 1

It helps if you write the formula correctly, so HCO-3 should actually be HCO₃^-

NO-2 should actually be NO₂^-

Now we have HCO₃^- + NO₂^- ==> HNO₂ + CO₃^2-

The HCO₃^- gave away a proton making it an ACID.

The NO₂^- accepted the proton making it a BASE

The HNO₂ formed now has the proton (H+) making it the CONJUGATE ACID

CO₃^2- wants to accept a proton making it the CONJUGATE BASE
