General Chemistry
Properties of Acids and
Bases Experiment Kit —
Lab-Aids ® No. 82
Students perform a total of seven
different exercises that involve acids
and bases. Hydrogen gas is prepared
by each student in an exclusive,
safe manner. Exercises include
reacting various metals with acids
and producing hydrogen in safe
quantities; collecting and safely testing
hydrogen; reacting carbonates
with acids and producing carbon
dioxide; collecting and testing carbon
dioxide; observing the effects
of acids and bases on indicator dyes;
measuring the concentration of
acids by titration of an “unknown”; and performing a neutralization experiment. Complete for
50 students. Sh. wt. 2.95 kgs.

SA08523M Refill (chemicals only). Sh. wt. 1.36 kgs. — $91.35
Chemical Equations I
Introduce students to chemical equations involving
singular replacement and double replacement
reactions. Student have the opportunity
to perform two different single replacement
reactions and two different double reactions.
Observed are colour change, formation of
precipitates, and production of gases. Includes
term sheets, activity sheets, laboratory exercises,
a crossword puzzle, and a test. Activity sheets
give the students practice in writing chemical
symbols and formulas for elements and radicals
(polyatomic ions) and writing formulas for compounds.
This kit is designed for 28 students working in groups of 4. Experiment
can be repeated twice. Grades 7—12. Sh. wt. 1.94 lbs.
SB43452M — $99.40
Characteristics of Matter Kit —
Kemtec
This kit allows students to explore the
characteristics of matter such as colour,
odour, solubility, density, alkalinity, acidity,
states of matter, texture, boiling point, and
melting point. Students also get the opportunity
to observe chemical properties of
five solutions by observing their reaction
with other solutions. From these reactions,
students then determine the names of
the two unknown solutions. Includes a
reproducible manual with 10 activities or
laboratories, vocabulary lists, vocabulary
definitions, and a complete answer key.
Activities and laboratories include properties
of matter, states of matter, properties
of solids and liquids, and more. Grades
5—7. Sh. wt. 1.56 kgs.
SB21299M — $146.70
Identification of
Chemical Reaction
Kit — Lab-Aids ® No. 84
Students learn through standard
laboratory procedure to identify
three types of chemical reactions:
colour changes, precipitates, and
gas generation. Seven known
solutions are mixed into any of
21 possible combinations by the
students, and then observed.
Complete for 50 students. Sh. wt.
2.49 kgs.

pH Measurement/
Indicator Kit —
Lab-Aids ® No. 81R
You no longer have to shortchange
your students’ lab experiences
because of the difficulties and
expense in preparing buffered pH
solutions. This kit solves that problem
and eliminates the chances for
contamination of reagents through
student carelessness. All of the buffers
and indicators are pre-mixed and
housed in spill-proof, contaminantproof
bottles. Kit contains enough
material for 30 students working in
teams to perform the experiments
individually. Sh. wt. 1.70 kgs.
SA08228M — $119.30
SA08520M Refill (chemicals only). Sh. wt. 0.48 kgs. — $79.45
Chemiluminescence
Lab Activity
Teach students about physical and chemical
reactions that involve the release of light and
heat energy. Students will learn about a lightemitting
reaction called chemiluminescence, or
“cool light.” They will create a chemiluminescent
reaction in the classroom, and then observe the
fascinating blue glow of the reaction, which lasts
for over 10 minutes. Includes fifteen 25 ml bottles
of luminol solution, 25 ml of 6% hydrogen peroxide,
fifteen 30 ml plastic cups, and 15 transfer
pipettes. Enough materials for 15 groups. Grade 7
and up. Sh. wt. 3.50 lbs.
SB46579M — $61.30
Flame Tests and
Emission Spectroscopy
Experiment Kit —
Lab-Aids ® No. 111
This kit introduces the entire concept of
spectrum analysis. By using spray mist
bottles to introduce safe water solutions
of various salts through a Bunsen flame,
tests of metallic ions are observed with a
spectroscope. Complete for 50 students.
Sh. wt. 1.16 kgs.

Fireflies: ATP/Bioluminescence Kit
Learn about the production of light by identifying
major components of a chemiluminescent
process in a living
organism — the firefly. Students
set up an actual bioluminescent
using firefly material and ATP. Kit
includes: five powdered firefly
lantern extract, five powdered ATP
(adenosine triphosphate), 30 glass vials,
teacher’s manual, and student copy
masters. Contains enough materials for
15 groups. Grades 7—12. Sh. wt. 2.25 lbs.

Very stable and easy to use red cabbage
extract powder. A safe, all food grade material
with low odour and a long shelf life. Will
make several gallons of strong red cabbage
juice. Includes: 20 g Red Cabbage Jiffy Juice
(red cabbage extract, dextrose, and citric
acid), plastic beaker, small scoop, pipet, pH
