  15. Writing Double Replacement Reactions GROUP WORK RULES: * Every student is responsible for their part – 100% effort ** Struggle, get stuck, then ask each other before calling a teacher *** Keep markers capped – Group Leaders are the marker monitors! • Pick a card – Write reactants (check BCD’s work after each step) • B. Write the ions and then formula for one product • C. Write the ions and then formula the other product • D. Write (aq) or (s) for each product [using solubility rules] • A. Will there be a rxn and precipitate? • Celebrate! • Rotate jobs, draw a new card, start again

Reactants Products • KPb+ I-NO3 • KNO3 + PbI • KNO3 + PbI2 • D) Pb(NO3)2 + KI The demo featured the reactants potassium iodide and lead (II) nitrate, which produced a cloudy-yellow precipitate. Which of the following choices represents the correct products of the reaction?

  20. Double Replacement Reactions 2 soluble compounds dissolved in H2O switch ions AX + BY  BX + AY

  21. Double Replacement Reactions BACKGROUND: Chemists can synthesize [make] different colored solids through ___________ - _________________ ______________. In this kind of chemical reaction, two ______________ reactants OR ______________ [meaning dissolved in H2O] compounds are mixed. Once dissolved, the compounds now exist in solution as free ________ and_____________. Sometimes, the ions combine to form a new ________________ [ meaning does NOT dissolve in water] compound. This new insoluble solid product is known as a ___________________ Chemists use the “__________________ ___________” to predict whether or not a precipitate will form in a double-replacement reaction. Generally, a precipitate will look ____________ and you may be able to see a new colored solid floating or settling to the bottom of the solution. replacement reactions double soluble aqueous cations anions insoluble precipitate rules solubility cloudy

  22. Procedure For each reaction write the word and chemical equations, use the _____________ to determine which ____________ will form by switching the _____________ . Use the _____________ of the ions to balance the _____________ . Use the solubility rules to predict whether the products will be soluble or if there will be an insoluble precipitate. Use ____ for “no reaction” or _____ for “precipitate”. If ppt, write the name of the product that you predict will precipitate. Once you have finished writing all reactions and making all predictions, ask your teacher for the solutions. Test your prediction for each reaction by mixing ___ _______ of each solution in a spot plate. Record observations for each reaction. Describe the precipitate if there is one (ex. ______________________ etc.) reactants products cations formulas charges NR ppt 5 drops color, cloudy, gel
