Water
Deionized W0007 4 liters $9.85
Distilled W0001 4 liters 9.37
Storage: Miscellaneous nonhazardous material.
Disposal: #26b
Shelf Life: Indefinite if kept tightly closed. If your distilled water is stored for
a long period, it will gradually become acidic, due to the presence of dissolved
CO2. Boiling the water before use will drive off and eliminate the dissolved CO2.
Color and Odor: Colorless, odorless liquid.

Z0005 500 g $23.00
HAZARD ALERT: Zinc dust can be a dangerous fire risk; may form explosive
mixture with air. If allowed to get damp in a confined bottle, heat will be
generated and the mixture may even ignite; cases are known where bottles
have exploded under pressure. Keep this product dry!
Storage: Inorganic #1
Disposal: #26a
Shelf Life: Good if kept dry. Store in a Flinn Chem-Saf ™ Bag to ensure it is
kept dry.
Soluble: Acids and alkalies; not water.

Z0002 500 g 45.50
HAZARD ALERT: Zinc metal dust could be flammable; dust may be present
at the bottom of your bottle of this form of zinc.
SPECIAL HAZARD ALERT: Granular zinc is often used. See in a classic
lab experiment to turn copper pennies into “silver” and then “gold”. See
the Gold Rush Chemical Demonstration Kit on page 356. Do not use sodium
hydroxide in this reaction—the leftover basic zinc residue is a fire hazard.
Call or write us to obtain a complimentary copy of a revised procedure for
this demonstration using granular zinc and zinc chloride. Visit flinnsci.com to
access publication No. 10991, Turning Copper Pennies into “silver” and “gold!”
Storage: Inorganic #1
Disposal: #26a
Shelf Life: Indefinite
Soluble: Acids and alkalies; not water.
Color and Odor: White/gray, odorless solid.

Zn Z0003 500 g $25.75
Z0004 2 kg 69.00
HAZARD ALERT: Zinc metal dust could be flammable; dust may be present
at the bottom of your bottle of this form of zinc.
For hazard alert, storage, disposal, etc., see Zinc, Granular, Z0028.
Technical Note: Due to the high purity of this zinc, it will not sufficiently
produce hydrogen gas when introduced to an acid. The reaction can be
catalyzed with a few mL of 0.5 M copper sulfate.
