HST has provided two lists, one for ordering the chemicals needed for our experiments and another list for ordering equipment and supplies. (Either click the URL or copy/paste it into your browser). ChemExplained.com Chemical List: https://www.homesciencetools.com/wishlist.php?publicwishlist=bbdd79a3ffdb49bea2f6190f1ed516ca

From the HST staff: “Please note that adding all items in a wish list at once will only add 1 item, please advise parents/students to adjust quantities on the items accordingly.” ——————————————————————————————————————————— Please READ THIS before ordering. A number of ChemExplained.com experiments require heat. The heat source listed below in our Equipment list is a propane or butane torch kit. These may be purchased at Home Depot, Ace Hardware or Mills Fleet Farm stores for ~ $25. The replacement butane or propane gas refill containers for these torches cost ~ $4. When these torches are used in an experiment, they must be “hand-held,” because if they are left upright while lit, they can tip over and cause a fire hazard. Home Science Tools (HST) sells a Portable Micro Lab Burner for ~ $52. Butane fuel refill cartridges cost ~ $6. This burner is “tip-resistant” and provides safe, stable operation during an experiment and is recommended, but it cannot be used for Lab #6. In all of our experiments, no burner of any kind may be used without adult supervision.
Laboratory balances are also required in a number of experiments. Balances accurate to 0.01 g (1/100th of a gram) provide the best results. However, lab balances accurate to 0.1 g (1/10th of a gram) can also be used. Amazon.com sells an AMIR Digital Kitchen Scale for ~ $12 (accurate to 0.01 g). Recommended! HST sells an Economy Pocket Scale for ~ $15 (accurate to 0.1 g)
In Lab #9, a Molecular Model kit from HST costs ~$22. A bag of colored marshmallows plus toothpicks can also be used for ~ $4.
Amazon.com (Industrial & Scientific area) has many of our items listed at discount prices. ———————————————————————————————————————————

- Laboratory balances that are accurate to a tenth of a gram (0.1 g) can also be used if your balance doesn’t record to the hundredth of a gram. Mass measurements in this lab will be to the 0.01 g. if possible.
LAB #4 laboratory balance 10 mL graduated sealable plastic 50 mL beaker (0.01 g) or (0.1 g) cylinder sandwich bag dropper pipet baking soda vinegar scoopula test tube brush Dawn soap
* Note - Mass measurements in this lab will be to the nearest 0.01 g. However, lab balances that are accurate to a tenth of a gram (0.1 g) can also be used. This will be the case for all future laboratory experiments.

- Corks not available? Use toothpicks to connect to the chromatography strips and use plastic wrap to cover the top of the test tube to prevent evaporation of the solvent. - Please follow directions carefully in this experiment. You may have to do it 2-3 times to get good results. Each time you do an experiment, it is called a “trial.” - The felt-tipped markers cannot be permanent markers, they must be water-soluble. - Smaller test tubes may also be used if larger ones are not available. - When inserting the chromatography paper into the test tube, don’t “splash” the solvent up onto the paper strip. The solvent must start out below the dye on the point of origin. - Students can design experiments to identify the dyes in colored food products such as M&Ms or Skittles. Place candy in 5-6 drops of water. Stir until the candy dissolves. Do lab.
LAB #11 potassium chlorate manganese dioxide crucible & cover
propane/butane torch (or micro burner) forceps clay triangle ring stand with ring clamp scoopula or spatula laboratory balance
* Note
- Please be careful in handling the potassium chlorate. Do not grind or crush KClO3 or mix it with other chemicals unless told to do so.

Master Lab Equipment and Supplies List for ChemExplained.com 6
hot pad holder or gloves ring clamp bottled water wire gauze coffee filters funnel clay triangle Dawn soap small metal cookie sheet/cake pan washing bottle (squirt bottle)
* Note - Use caution in measuring the potassium chromate and lead nitrate. Measure out the amount you need and dissolve the chemicals in water as soon as possible. - Laboratory balances accurate to 0.1 g can also be used. - Do not use a stirring rod in this experiment. Carefully “swirl” the beakers instead to dissolve the contents.
LABS #14 - #15 hydrated copper(II) sulfate aluminum wire 3.0 M hydrochloric acid
propane/butane torch (or micro burner) test tube brush evaporating dish ring stand stirring rod or scoopula laboratory balance 250 mL glass beaker 25 mL graduated cylinder butane lighter washing bottle (squirt bottle) ring clamp bottled water wire gauze coffee filters funnel pocket microscope Dawn soap forceps microscope glass slide paper towels small metal cookie sheet/cake pan scissors or wire cutter 12” ruler sodium chloride, NaCl
* Note - This experiment is performed in parts over three days and counts as two lab experiments. The student may stop and start at any time, however, they should add water (bottled) to any solutions that have evaporated. - “Hydrated copper(II) sulfate” is copper(II) sulfate pentahydrate. - A tripod magnifier (or magnifying glass) may be used instead of a pocket microscope. - Laboratory balances accurate to 0.1 g can also be used. - 32-36% hydrochloric acid may be used in lieu of 3.0 M HCl It is possible to perform this experiment without using the 3.0 M HCl, (3 molar hydro- chloric acid) but it may result in a slightly higher percent error.
LAB #16 18 mm x 150 mm test tube copper coated steel BB’s test tube holder Master Lab Equipment and Supplies List for ChemExplained.com 7
thermometer bottled water (room temp.) 12 oz. styrofoam cup ring stand ring clamp saucepan from kitchen micro lab burner wire gauze kitchen stove 600 mL or 800 mL beaker laboratory balance
* Note - Instead of using a ring stand, ring clamp, wire gauze, 600 mL or 800 mL beaker and propane/butane torch or micro lab burner, this experiment can be done with a saucepan of boiling water on the kitchen stove. - A styrofoam cup is used as the calorimeter in this experiment. - A laboratory balance accurate to 0.1 gram may be used. - The exact size of the test tube is not critical, one of similar sizes may be used. - Record temperatures to the nearest 0.1°C throughout the experiment. - If your laboratory balance ever gives you an “error”or “overload” message of some kind, measure out smaller amounts of your substance at a time and then add them together.
LAB #17 6 soda pop cans, Al (empty) copper(II) chloride (~3.0 g) funnel and gloves triangular file or long nail 250 mL or 400 mL beaker laboratory balance stirring rod or spatula 100 mL graduated cylinder small cake pan
* Note - Copper(II) chloride, either anhydrous or dihydrate may be used in this experiment. - The student should have their Ch. 9 notes available during this lab activity. - A 250 mL beaker and 50 mL graduated cylinder can be used in lieu of the 400 mL beaker and the 100 mL graduated cylinder. - A long nail (6” to 8”) may be used instead of a triangular file.

* Note - Sodium hydroxide (NaOH), can be purchased from Home Science Tools in a 30.0 gram bottle. The student needs exactly 2.00 grams of NaOH for this experiment. - Any beakers sized 100 mL to 400 mL beakers can be used. - The size of the Erlenmeyer flask must be at least 100 mL in volume. (100 mL to 400 mL) - Review your Ch. 18 notes on Titration (including the diagram) before starting this activity. - If you can’t find a cork, use a baggie and rubber band to cover the top of the Er. flask. - This is a fairly short experiment, but it takes a lot of explanation. Pay attention to details! - Vinegar is composed of acetic acid (HAc) dissolved in water.
