Stoichiometry lab mass-mass and limiting reactant purpose in this lab, you will determine the reaction for mixing two reactants together you will then measure out 0005 moles of each reactant. In the first day students design their lab, which includes solving a stoichiometry problem on the second day they conduct the lab, and on the third day they write and critique their lab report in this lesson students learn how to design an experiment in which they can evaluate how closely an experiment’s actual yield corresponds to the.
To determine the limiting reagent in a reaction through a measured quantity introduction in this lab, you will be investigating reaction stoichiometry by doing a series of mixing experiments using acids and bases in different amounts.
Resource topic: stoichiometry the mole, molarity, and density autograded virtual labs creating a stock solution autograded virtual lab in this activity, students use the virtual lab to create dilute solutions from a concentrated stock solution of acids or bases. In this lab, you will be investigating reaction stoichiometry by doing a series of mixing experiments using acids and bases in different amounts by following temperature changes upon mixing, you will be able to relate the amount of heat given off in the reaction to the moles of acid and base that react.
This lab is adapted from: kristen l cacciatore and hannah sevian, teaching lab report writing through inquiry: a green chemistry stoichiometry experiment for general chemistry, journal of chemical education, 83(7), 1039, 2006 4-1. Target stoichiometry lab continued 2 216 linn scientiic nc ll rights resered tips • be sure the test tubes used are borosilicate glass inspect the test tubes for chips or cracks before using. This is the lab procedure in which students produce a calcium carbonate precipitate by reacting calcium chloride with sodium carbonate they then filter and dry the precipitate and weigh it to compare to a stoichiometric calculation.
Target stoichiometry lab mole relationships and the balanced equation introduction a simple decomposition reaction of sodium bicarbonate (baking soda) presents the opportunity for students to test their. Stoichiometry lab: the determination of the mass of product of a chemical reaction 2 2 using your bunsen burner, gently heat the beaker and its contents until all the liquid is driven off leaving behind the solid.
A simple decomposition reaction of sodium bicarbonate (baking soda) presents the opportunity for students to test their knowledge of stoichiometry, factoring labels, and the mole concept this outcome-based lab requires the students to precisely predict the mass of the solid product an electronic balance will reveal how close the students come to their “target” and determines their grades. There is a traditional stoichiometry lab i have done before it involves adding dilute hydrochloric acid to sodium bicarbonate, boiling off the fluid and then getting the mass of the sodium chloride students then can solve the percent yield for the sodium chloride based on the amount of sodium bicarbonate they use it is not a bad labsomething about having hot ceramic watch. This lab is designed to provide data which demonstrate the validity of the mathematical techniques of stoichiometry by both calculating the amount of caco 3 that forms and measuring it in the lab it will be possible to calculate the percent yield for the reaction.
