Answer #1

according to bronsted lowry acid base concept, the compuond which accept a H+ is a acid and which donates a H+ is base.

here in the equation, CN- accpets a H+ to form HCN and H2CO3 donates a H+ to become HCO3- also in reverse reaction HCN donates a H+ to form CN- and HCO3- accepts a H+ to form H2CO3

bronsted lowry Acid : H2CO3 and HCN

Bronsted lowry Base : CN- and HCO3-  

conjuate acid base is differed by one H+

so Conjugate acid of CN- is HCN

Conjugate base of H2CO3 is HCO3-
