Molecular Formula. Why does a salt containing a cation from a weak base and an anion from a strong acid form an acidic solution? Really strong bases such as NaOH or KOH with a really strong acid, such as HCl will give a neutral solution. Their function varies depending on the dye class. Insert an indwelling urinary catheter HCN: This is an acidic compound because HCN can donate a proton (H+) to water to form H3O+ and CN-, which is the conjugate base of HCN.
