Weak acids:
are always more soluble than strong acids
have a higher degree of dissociation than do strong acids
only ionize a fraction of their molecules
always produce weak conjugate bases

Weak acids only partially ionize. so the retain part of the original molecule. C

The answer would be c. fish
