Recall the Law of Conservation of Matter (or Mass) • The Law of Conservation of Matter states that during a chemical reaction, matter is neither created nor destroyed. In this lab experiment, three substances are placed in a plastic bag. Pour 10 mL of cabbage juice into a small vial. What questions arise concerning the changes that were observed during the reaction in the bag? This could be used as an example of chemical reaction that releases energy (exothermic). Hold a reaction in your hand, literally, as students observe and ask questions. This gas fills the bag until the bag explodes. A reaction between an acid and a base is called a neutralization reaction because the reactants (acid & base) are always neutralized into water and a salt. Pass the bag around and have all group members look at and feel the contents of the bag. Learn about reactants, products, and observations. One of the main contributors to the love of this topic is the BARF BAG lab. Part 2: Mixing the two reactions.

This lab is a great hands-on approach for introducing students to the process of how reactants chemically Once your planning section is approved, carry out the reaction and inflate the bag or bags according to your design. Zip the bag closed and shake it to observe for any evidence of a chemical change. So, the products of neutralization reaction are always water and some type of salt. By 2 seconds after the initial impact, the pressure inside the bag has reached atmospheric pressure. Reaction in a Bag — The Wonder of Science. One illustrative example is the acid-base reaction which occurs when an acid reacts with a base. Grades 7–12. Being careful not to spill any of phenol red solution, place the vial in an upright position into the bag of powders and seal the bag tightly. Objectives. If you perform this reaction in a plastic bag, the bag expands. Is this an oxidation reduction reaction or a metathesis reaction? Please justify your answer. When the baking soda and vinegar mix, they create a chemical reaction that produces gas (carbon dioxide in this case). Measure 1/2 cup of vinegar into the snack size ziploc bag and zip the bag closed. 2. 6. . That said, when we did the experiment a second time, we shook the bag way too violently. 21. Clean-Up : Empty the bag’s contents into the sink, wash out medicine cup, and wash out bag. Reaction in a Bag allows you to hold a reaction in your hand, literally, as students observe and ask questions. Open the plastic bag and set That reaction produces potassium silicate and sodium silicate, both of which stop the sodium from reacting with moisture in the air to form corrosive sodium hydroxide. Gauge pressure + atmospheric pressure = absolute pressure. These reactions often produce The Baking Soda and Vinegar Reaction. Get as much air as possible out of the quart size bag before zipping it closed. wardsci. Place ½ teaspoon of sodium bicarbonate into the plastic bag 2. 7.
