I do not want to sound like a gossip maker but recently I was informed that
there is a possible reaction between Baking Soda and Ammonia that can
produce cyanide ion. Is that true? |

I have never heard of anything like this. It is certainly not
something that will happen with casual household use.

Some brands of bleach tell you not to put bleach close to detergent.
What>s their theory, they>re not in the laundry biz?
I think it started with Eisenhower, and went downhill fronm there:
everywhere you look, goddam wingnut squawkers.

I don>t know what the reason for this would be except for legal
CYAism. I put bleach in with detergent all the time when washing
white clothing. That>s what it>s made for.

The warning I>ve seen is not to put bleach near other *cleaners*. I suspect
you read this and extrapolated "cleaners" to mean detergents. What they
really mean is not to put it near bathroom cleaners, because a lot of
bathroom cleaners contain HCl, and exposure to the resulting Cl2 fumes in a
small, unventillated bathroom could *really* ruin your weekend.

Nonconfrontational facts about household chemicals Mentioned here earlier was
"the vast amount of chlorine given off by reaction of Clorox (about a 51% solution of
sodium hypochlorite) with products like Vanish, detergents, and ammonia" (C&EN,
Sept. 19, 1988, page 56). These words being slightly off the mark, an anonymous
correspondent wishes "to point out a few facts in a nonconfrontational manner."
He or she writes that a pH dependent equilibrium exists among hypochlorite,
hypochlorous acid, and chlorine. "Above pH 7.5, hypochlorite ion predominates. Some-
where around pH 5 it becomes possible for free chlorine to exist in solution. The rub is
that chlorine is much less soluble than either HOCI or OCI, and at about pH 2 or 3 it
comes boiling out. This is why you don>t mix chlorine bleach with acids. A
garden-variety toilet bowl cleaner is usually a moderately strong acid such as
phosphoric acid or sodium bisulfate, which easily delivers a pH around 2. It>s amazing
how much chlorine you can get out of a pint of bleach. That>s why products like Clorox
bleach and Vanish toilet bowl cleaner carry ... warning notices on their labels. Isn>t it
amazing how few people bother to read?"
Ammonia is a different case, the correspondent goes on. "Mix an ammonia solution
with hypochlorite and you get chloramines-NH2Cl, NHC12, and NC13. The chloramines
are alkaline but less soluble than ammonia, so they bubble out. They are also
poisonous. That>s what happens when you mix hypochlorite bleach with household
ammonia.
"So what happens when you mix bleach with detergents? Clean clothes."
