How would you identify the acid, base, conjugate acid and conjugate base in the following reaction: HCN + SO4^(2-) --> HSO4^(-) + CN^(-)?
Acid, hydrogen cyanide, "Prussic" acid; base, sulfate ion. The conjugate species is idenitified by proton addition OR removal.
The conjugate acid is simply the starting material PLUS a proton; the conjugate base is simply the starting material MINUS a proton. Both mass and charge are conserved. SO the conjugate base of sulfuric acid,
What is the conjugate acid of sulfuric acid,
