An unknown salt is either kbr, nh4cl, kcn, or k2co3. if a 0.100 m solution of the salt is neutral, what is the identity of the salt?

I would say that this problem needs more information. Giving only the concentration would not specify anything since in general salts are neutral as they are from neutralization reactions. Specifying other properties of the compound would be more helpful.
