WebYes, it is true that the stronger an acid the weaker its conjugate base. And yes, you probably learned about strong and weak acids. And often that is where it is left. And many students have come into my Chemistry classes believing that the conjugate base of a weak acid is a strong base and vice versa. WebCyanide is a weak base for two main reasons. One is because like you said, it is the conjugate acid of a moderately weak acid HCN, making CN- a weak base as well. If HCN was an EXTREMELY weak acid (say pKa~ 1.0. x 10-30 or so) then CN- would be considered a strong base. The important reason, however, why CN- is a weak base is because the ...

WebAug 14, 2024 · The conjugate base of a strong acid is a very weak base, and, conversely, the conjugate acid of a strong base is a very weak acid.
