I wonder how many accidental poisonings occurred?
I remember old chemistry sets came with sodium ferrocyanide. The
bottles all said "DO NOT MIX WITH ACID" with no explanation given,
which probably lead to a few children trying it to see what happens.
Fortunately the acids available in the chemistry sets weren't very
concentrated, as a strong acid mixed with sodium ferrocyanide can
produce cyanide gas, esp. when the solution is exposed to heat or
direct sunlight. Also fortunate is the bond between the iron and
the cyanide in sodium ferrocyanide is very strong.
I wonder if children's chemistry sets still come with all the
interesting chemicals?
