Though I demonstrated some basic safety tips, how to set up their apparatus, and the general approach to performing the reaction, the bulk of the experimental design was going to be on them. After thinking about it a bit, there were at least five distinct features that convinced me to pursue this lab. Students will also determine that these are both endothermic reactions based on their observations. Their task: Figure out which balanced chemical equation accurately represents the decomposition of sodium bicarbonate. Decomposition of sodium bicarbonate stoichiometry lab answer key. When this happens, we think about how we can improve the experiment and do it over again. Follow the simple instructions below: The days of terrifying complicated legal and tax documents are over.

Decomposition Of Baking Soda Stoichiometry

It could be that this is due to an error you made... or maybe the stupid sodium bicarbonate didn't get the memo that, according to the teacher (or the text or Wikipedia or whatever), it was supposed to decompose to sodium carbonate, so it just went ahead and decomposed all the way to sodium oxide. Doing so resulted in the reaction seemingly taking forever to complete. In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. Please consider taking a moment to share your feedback with us. Every weighing must be carefully done in order to obtain good results. To explain this, they need to dig deeper into the data and convert masses of reactants into moles. Make a detergent solution by adding 1 teaspoon of liquid dish detergent to 2 tablespoons of water. In this lesson, students will extract DNA from strawberries and analyze evidence to figure out who perpetrated a petty crime. Teacher Preparation for the Demonstration and for Each Group. When trying to explain how their percent yield was over 100%, several groups initially struggled to realize they had just simply stopped the reaction too soon. The theoretical amount of NaCl that can be produced from a weighed amount of NaHCO3 and excess HCl is given by: The percent yield is given by: USE OF LABORATORY BALANCE. Or they can result from the need to provide better solutions to a problem. Once all of the solid has dissolved, continue to add HCl but now do it dropwise (agitating the test tube after each drop). Experience a faster way to fill out and sign forms on the web.

Baking Soda Stoichiometry Lab Answer Key Tpt

Decide on how much vinegar and baking soda you will use and write these amounts in the chart on the activity sheet. Repeat steps 7 and 8 with test tubes 2 and 3. When an equation of a chemical reaction is written, it is "balanced" to show this. Do a demonstration using Alka-Seltzer or a similar effervescent tablet in water to show that citric acid reacts with sodium bicarbonate to produce carbon dioxide gas. Maybe some of the mixture in the crucible splashed out during the reaction. Get access to thousands of forms. Also be sure that they see that there is an equal number of each type on both sides of the equation. As an instant download, an attachment in an email or through the mail as a hard copy. While merit for such a lab can be argued for, I really wanted to immerse my students in an actual investigation that more accurately reflected the scientific skills I try to advocate for—experimental design, data collection, analysis, creating an argument from evidence, engaging in argument, etc. 1 clear plastic cup. Dioxide gas in Experiment #2.

Mathematical and computational thinking at the 9–12 level builds on K–8 and progresses to using algebraic thinking and analysis, a range of linear and nonlinear functions including trigonometric functions, exponentials and logarithms, and computational tools for statistical analysis to analyze, represent, and model data. You can either: - Massage the result of your experiment until it comes up with the answer you think is "supposed" to be correct. Sometimes it is hard to reduce, let alone eliminate, previous conceptions and biases when asking students to develop an argument from evidence. 40 g. How can this be? We had just finished our reactions unit, so they were all familiar with the generalized pattern that a decomposition reaction follows. Using less baking soda, for instance, produces less carbon dioxide gas because there are fewer atoms from the baking soda to produce the carbon dioxide. In a chemical reaction, only the atoms present in the reactants can end up in the products. Add ½ teaspoon of baking soda to the empty graduated cylinder. CHE L110 - Chemistry and Society Laboratory. For example, in the demonstration baking soda was placed in the graduated cylinder before the vinegar and detergent were added. In the vinegar and baking soda reaction, the atoms in the CO2 only come from the sodium bicarbonate.

Students will be able to count the number of atoms on the reactant side and on the product side of a chemical equation. Two gases actually form during most baking processes. As the temperature of the cake batter reaches approximately 50oC, the baking soda decomposes and carbon dioxide is released. Some groups only recorded the mass of their sodium bicarbonate, without considering the mass of their test tube and glass stir rod. Look at the teacher version of the activity sheet to find the questions and answers. What is the gas produced in the chemical reaction between vinegar and baking soda?
