Hydrochloric Acid continued Hydrogen Peroxide continued
3% H0009 473 mL $ 5.00
laboratory grade H0038 3.8 liters 18.40
HAZARD ALERT: 30% hydrogen peroxide requires special storage and
handling procedures. It is a very strong oxidizing agent and severely corrosive
to skin, eyes and respiratory tract. Many common substances, including iron
and other transition metals, will catalyze the decomposition to produce copious
amounts of oxygen gas and heat. The 30% solution is a dangerous fire
and explosion risk—do not heat. Wear appropriate protective clothing. TLV 1.4
mg/m3. Dilute 3% and 6% hydrogen peroxide solutions are weak oxidizers and
skin and eye irritants.
Storage: Inorganic #6. We frequently find 30% hydrogen peroxide stored in
school refrigerators. We do not recommend storing any laboratory chemicals
in household-type refrigerators.
Disposal: #22a
Shelf Life: Fair to poor; when stored at room temperature, the substance
decomposes at approximately 0.5% per year.
Soluble: Water and alcohol.
Color and Odor: Colorless, odorless liquid.
CAS No. 7722-84-1

meet or exceed DIN standards and are nondrying and nonhardening. Use
low viscosity between the objective and slide; use high viscosity between
the condenser and slide.

Incompatability: Avoid storing hydrochloric acid anywhere in the vicinity
of formaldehyde. A potent carcinogen, chloromethoxychloromethane, is
formed when hydrochloric
acid and formaldehyde react in air. This serious
potential problem further emphasizes the need to store hydrochloric acid in
a dedicated acid cabinet.
Safety Purchase Suggestion: Buy and store only small package sizes
and small quantities. For safety reasons, Flinn offers larger sizes of hydrochloric
acid and other hazardous substances
in PVC-coated bottles. We have
attempted to price the products in these safer containers as low as possible.
*Hydrochloric acid is exactly as described under catalog number H0005 but in
a PVC-coated bottle. In the event of breakage, acid and glass shards are safely
retained in a PVC outer envelope. The PVC-coated bottle is a safer package
for science teachers.
SPECIAL STORAGE TIP: Hydrochloric acid fumes a lot—particularly
when warm. These fumes are responsible for most of the corrosion damage in
your acid storage area. To solve this problem, store hydrochloric acid bottle(s)
in a tightly sealed plastic bag. Be sure to label the outside of the plastic bag
since acid fumes will soon destroy the bottle label. Spray the label on the
bottle with Krylon® plastic spray (AP1559, page 1165) if you wish to preserve it.

The Package Can Be Dangerous!
Those of you whose school administrations allow the unsafe practice of
“bidding” laboratory chemicals to continue will find an interesting example
of trouble from “low bid” chemicals. Read the special hazard alert for calcium
oxide and ask yourself whether your “low bid” chemical meets these safer
packaging standards. None of our competitors package the substance to
these standards. With bids, you get what you pay for!
