Question

Consider the reaction below. Which species are conjugate acid/base pairs?

HSO₃^-_(aq)+HCN_(aq) $\rightleftharpoons$ H₂SO_3(aq)+CN^-_(aq)

Answer 1

the conjugated acid pair HSO3 (Base) → H2SO3 (conjugated acid), the conjugated acid pair HCN (Acid) → CN- (conjugated base), ---------- ----------------------------------------- Acid is the substance that can donate a proton (H) baseis the substance that can accept a proton (H+) The pair of acid – base which is differ by a proton(H+) is called conjugated acid – base pair HSO; + HCN + H2SO4 + . CN Base conjugated acid conjugated base Here HSO; is base after accepting proton it is converted to conjugated acid H,SO; Here HCN is acid after donating proton it is converted to conjugated base CN the conjugated acid of HSO, is H,SO2, while the conjugated base of HCN is CN- Acid
