I want to know if there is any problem with storing chemicals such as,
kno3, kclo4, kclo3 in plastic containers rather than in a bag in a
plastic container. I ask this because when i purchase chemicals they
always come in a bag in a container and i like when they are just in
the container they are easier to work with and having a bag kinda makes
a mess with ceartin chemicals. The oxidizers i listed i have alot of
and they are in fairly air tight containers. Also how long do most
common oxidizers last? i usally use them up fairly quickly anyway. i
want to know im still kinda new to this hobby. thanks |

I would say if you kept them in a sealed container they would last many
many years, 10+. Of course that is if they are not exposed to extreme
temperatures, or moisture. Black powder is listed as being stable
indefinately in proper storage. Just keep them sealed and in a cool,
dry place. |

I would say that really covers it. The influencing factors (heat, UV,
moisture etc) would be the few intruding issues. But there are
instances wherein various chemical compounds were stored for many,
many years in an amber bottle on a shelf. Now if we extrapolate that
you maintain the chemical in a plastic bag and that bag is inside a
tinted plastic tub ( such as you'd get from the various vendors) then
the issue gets back to how well were they sealed and if UV / moisture
can intrude into the tub....there are VERY few things I could think of
that in this hobby need to be kept at a purity level that such would
be a grave issue.

As far as the bags go......Although the shipping regulations via USPS (Pub
52, Haz Mat) do not state the need for a plastic liner. The reason is most
likely so that if the plastic container where to come off during shipment,
then the contents would leak into the box, which could leak out of the box,
then really cause some commotion with postal workers seeing some white
powder floating around. So, it is really just a precaution, from what I
read, that they are doing this. A sealed plastic bag inside of a sealed
plactic container should provide a pretty good transport container.

There should be no problem with storing the chemicals you mention in clean
plastic containers. Their shelf life is indefinite and largely depends on
storage conditions. If the containers are well closed and stored in a dry place,
the chemicals should keep for many years.

Forever. The only issue is keeping them dry, but even then dampness is
not irreversible. It might not be worth your trouble to re-dry and
re-pulverize a quantity of a certain damp oxidizer, but it's always
possible and usually feasible.

I should've added a general tip used when storing any chemical subject
to deterioration on frequent opening of the container: aliquot it.
That is, portion it into smaller containers first, as full as
practicable, and work from those, emptying one at a time.
