Chemistry Unit 7 – The Mole Lesson 11 – Predicting Products Part III – Double Replacement Book Section: 11.2 Objective: SWBAT predict the products of double replacement reactions using solubility rules. Agenda: Do Now, Lesson, Use of Solubility Chart, PSSA Reflection, Homework Do Now: Review - What are the five reaction classes and their generic formulas?

Double Replacement Double replacement reactions occur when two aqueous solutions combine, switch ions, and one ionic compound becomes a solid precipitate. Generic reaction: AX + BY AY + BX

Double Replacement Reactions Solubility rules govern which compounds will be solid precipitates and which will stay aqueous.

Double Replacement Reactions It appears the two ions in the reactants compounds exchange, or transpose, ions AgNO 3(aq) + KCl (aq) AgCl (s) + KNO 3(aq) You will need the following materials to determine products for double replacement reactions: Periodic table Ion table Solubility rules (receive today)

Double Replacement Reactions Given an apparent double replacement reaction… NaOH (aq) + MgCl 2(aq) Step 1: Determine the possible products of this reaction by switching partners.

Double Replacement Reactions Given an apparent double replacement reaction… NaOH (aq) + MgCl 2(aq) Mg(OH) 2 + NaCl Step 1: Determine the possible products of this reaction by switching partners.

Double Replacement Reactions Given an apparent double replacement reaction… NaOH (aq) + MgCl 2(aq) Mg(OH) 2 + NaCl Step 2: Use the solubility rules to tell whether or not a product is a solid precipitate.

Double Replacement Reactions Given an apparent double replacement reaction… NaOH (aq) + MgCl 2(aq) Mg(OH) 2(s) + NaCl (aq) Step 2: Use the solubility rules to tell whether or not a product is a solid precipitate. If neither of the two products is solid, write NO REACTION (NR).

Double Replacement Reactions Given an apparent double replacement reaction… NaOH (aq) + MgCl 2(aq) Mg(OH) 2(s) + NaCl (aq) Step 3: Balance the equation.

Double Replacement Reactions Given an apparent double replacement reaction… 2 NaOH (aq) + MgCl 2(aq) Mg(OH) 2(s) + 2 NaCl (aq) Step 3: Balance the equation.
