Give reason(s) for the product(s) 1. barium chloride + sodium sulfate → 2. calcium + hydrochloric acid → 3. The limiting reactant in a reaction: a. has the lowest coefficient in a balanced equation. As a rule, if A has a higher activity that \(B\), a single displacement reaction will occur. In this lab you will perform a variety of single and double displacement reactions. 6: Single and Double Displacement Reactions (Experiment), [ "article:topic", "authorname:smu", "showtoc:no", "license:ccbync" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FAncillary_Materials%2FLaboratory_Experiments%2FWet_Lab_Experiments%2FGeneral_Chemistry_Labs%2FOnline_Chemistry_Lab_Manual%2FChem_10_Experiments%2F06%253A_Single_and_Double_Displacement_Reactions_(Experiment), 5: The Composition of Potassium Chlorate (Experiment), 7: Mole Ratios and Reaction Stoichiometry (Experiment), Pre-laboratory Assignment: Single and Double Displacement Reactions, Lab Report: Single and Double Displacement Reactions, information contact us at info@libretexts.org, status page at https://status.libretexts.org. If no reaction occurs write the words "no reaction" (or NR) instead of the products in your balanced equation and indicate why your think there was no reaction. Write the balanced molecular equation (identical to what you completed in the previous section), the complete ionic equation and the net ionic equation for these reactions. \[\ce{Pb(NO3)2 (aq) + 2 KCl (aq) -> 2 KNO3 (aq) + PbCl2 (s)}\]. What is the general equation of a single displacement reaction? One such example is hydrogen sulfide (\(\ce{H2S}\)). For each of the following sets of reactants, write the balanced equation for the double displacement reaction that occurs. Inform your instructor of any chemical contact as soon as possible. Identify the reaction type – single or double displacement, using the guidelines outlined thus far. Some of the observable signs that a chemical reaction has occurred include the following: Note that there are many other observable signs for chemical reactions, but these are the ones most likely to be encountered in this lab. Aqueous potassium chloride + aqueous silver nitrate, 9. Analytical Chemistry Douglas A. Skoog, Donald M. West, F. James Holler, Stanley R. Crouch Aqueous zinc nitrate + aqueous lithium chloride, Hydrobromic acid + solid magnesium sulfite, Aqueous rubidium hydroxide + perchloric acid, Aqueous lithium chromate + aqueous gold(III) iodide. Aluminum metal + aqueous nickel(II) nitrate. If the word equation is complete, write and balance the chemical equation. Be sure to include the physical states of all reactants and products in your final equation. If the word equation is incomplete, complete it and write the balanced chemical equation. Thus, if results are not obtained immediately, give the reaction some time. 5.0 Approximately what mass of CuSO4•5H2O (250 g mol-1) is required to prepare 250 mL of 0.10 M copper(II) sulfate solution? When finished, complete your lab report by writing the balanced equations for each reaction studied. 2H2O2 2H2O + O2. Zinc metal + aqueous lead(II) nitrate, 12. Both carbonic acid and sulfurous acid are unstable and will decompose to form carbon dioxide and sulfur dioxide gases, respectively: The predicted products are sulfurous acid and sodium nitrate. For the reactions involving solid reactants (#2, 4, 5, 7, 11, 13), use the large test tubes. Balanced Molecular Equation (from page 1): Balanced Molecular Equation (from page 3): Predict the products for the following single and double displacement reactions, and write balanced molecular equations (including physical states) for each of them. Aqueous sodium phosphate + aqueous copper(II) sulfate, 5. 4.25. Note that if both of the predicted products are soluble, a precipitation reaction will not occur. Be especially cautious when using the 6 M \(\ce{HCl}\) and 6 M \(\ce{NaOH}\) as they can burn your skin. Use uppercase for the first character in the element and lowercase for the second character. If you determine that a reaction will not occur, write “NR”, and provide a brief explanation. Aqueous nickel(II) nitrate + aqueous sodium hydroxide, 8. The balanced equation for the reaction is 3O2 1g2 ¡ 2O3 1g2 To calculate the moles of O3 produced, we must use the appropriate mole ratio: 0.50 mol O2 lh h C b di b k i h h i d i i 2 mol O3 0.33 mol O3 3 mol O2 Avogadro’s law states that V an, which can be rearranged to give N2 H2 An Activity Series is provided at the end of the Background section. Use uppercase for the first character in the element and lowercase for the second character. Solutions: 6 M sodium hydroxide, 6 M hydrochloric acid, 6 M ammonium hydroxide, 5% acetic acid; all other solutions are 0.1 M and include silver nitrate, barium chloride, sodium sulfate, potassium chloride, lead(II) nitrate, iron(III) chloride, sodium carbonate, cobalt(II) nitrate, sodium phosphate, zinc nitrate, copper(II) sulfate, sodium chloride, potassium nitrate, nickel(II) nitrate. \[\ce{H2SO4 (aq) + 2 LiOH (aq) -> Li2SO4 (aq) + 2 H2O (l)}\]. If you determine that a reaction will occur, write the correct formula(s) of the products after the arrow. However, one of the products could also be carbonic acid (\(\ce{H2CO3}\)) or sulfurous acid (\(\ce{H2SO3}\)). Neutralization reactions are exothermic, and are generally accompanied by a noticeable release of heat. The balanced equation will appear above. However, if \(A\) has lower activity than \(B\), a single displacement reaction will not occur. Be sure to include the states of all compounds in your equations (solid, liquid, aqueous, or gas). An excess of NaOH … If Avogadro number N A , is changed from 6.022 × 1023 mol 1 to 6.022 × 10 20 mol 1, this would change (a) the mass of one mole of carbon (b) the ratio of chemical species to each other in a balanced equation (c) the ratio of elements to each other in a compound (d) the definition of mass in units of grams. For reactions involving solutions only, use small test tubes. C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l) 51 Determine the mass of CO2 produced when 9.0 grams of glucose completely reacts with 9.6 grams of oxygen to produce 5.4 grams of water. The metal should be completely immersed in the solution used. During a chemical reaction both the form and composition of matter are changed. What is the general equation of a double displacement reaction? If the new element \(B\)is a metal, it will appear as a metallic deposit. Academia.edu is a platform for academics to share research papers. The test tubes do not have to be dry. Include all physical states, and circle the spectator ions in the complete ionic equations. magnesium metal + aqueous aluminum chloride, Since \(\ce{Mg}\) is more active than \(\ce{Al}\), a single displacement reaction will occur.
