Solubility Rules Quiz-Quiz-Trade Line up when the bell rings A’s are outside circle B’s are inside circle

Labs go into black tray You will want PT, Solubility Rules, Packet

Fan&Pick Warm-up: clockwise Person 1: pick a card- ask the question in order Person 2: answers question A (SR or DR) Person 3: answer question B (activity series or solubility) Person 4: answer question C (does the rxn occur? Why?) Person 1 is checking answers the entire time. Coach them if it’s wrong using questions

Neutralization Reactions When you add an acid to a base The products are water and a salt (ionic compound)

HCl + NaOH HCl HCl dissociates into H+ and Cl- NaOH dissociates into Na+ and OH- H+ Cl- OH- H+ Na+ Cl- OH- H+ Na+ Cl- Na+ OH-

HCl + NaOH → NaCl + H2O HCl + NaOH No H+ or OH- remain to make the solution Acidic or Basic It is Neutral-ized Na+ is attracted to Cl- to form a salt H+ is attracted to OH- to form water H+ Cl- OH- H+ Na+ Cl- OH- H+ Na+ Cl- Na+ OH-

H2O + NaNO3 2H2O + CaSO4 3H2O + Na3PO4 No reaction! Acid soup! base 2H2O + CaSO4 base acid 3 3H2O + Na3PO4 base acid No reaction! Acid soup! acid acid 3 3H2O + Al(ClO4)3 base acid

Showdown Reaction Type Using your packet, determine the type of reaction, write and balance them. Rules for Showdown: Teacher chooses Showdown captain. Students answer the question solo. Timer signals Captain says “showdown”. All stand. Celebrate if all correct, coach peers if not. Write final answer on whiteboard for grading within given time limit. +5 correct, -2 if incorrect

Show Down Pg 7 #3 Pg 14 #6 Pg 7 #5 Pg 14 #1 Pg 9 f Pg 8 #10 Pg 11 #7 Pg 14 #7 Pg 9 g Pg 14 #14
