Now, potassium ferrocyanide is an approved anti-caking agent, and hence used in table salt, for example. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. The reason why this is so is because the cyanide ligands are very strongly bound to the iron (in slightly more technical terms the dissociation constant is very, very small (ca 10-24)). of either potassium ferro‐ or ferricyanide. What is the point of reading classics over modern treatments? Thanks for contributing an answer to Chemistry Stack Exchange! @OscarLanzi yes, typo.

Most of the mechanisms that generate cyanide require much more violent chemical attack: waiting for the cyanide to dissociate and then protonating it to give deadly HCN will never result in a notable amount of NCH. Despite the presence of cyanide, it is tightly bound (with ions) and stays within its atom until excretion. Table salt is often heated as part of cooking. But the answer to whether it is toxic is no! According to this answer, heating potassium ferrocyanide will decompose it into potassium cyanide. The compound can cause irritation in case of contact with skin and eyes.
