Dive into a detailed exploration of double replacement reactions, including acid-base neutralization and precipitation reactions. Learn how to conduct experiments, analyze data, and draw conclusions while ensuring safety measures are followed. Discover the significance of theoretical yield and percentages in chemistry experiments.

DOUBLE REPLACEMENT • A LABORATORY EXAMINATION OF DOUBLE REPLACEMENT REACTION www.assignmentpoint.com
SAFETY • GOGGLES • HAIR TIED BACK • APRONS www.assignmentpoint.com
CHEMICAL THEORY • THERE ARE MANY TYPES DOUBLE REPLACEMENT REACTIONS, SUCH AS ACID-BASE NEUTRALIZATION AND PRECIPITATION. www.assignmentpoint.com
PRECIPITATE REACTIONS • THESE ARE REACTIONS IN WHICH AN INSOLUBLE SOLID IS FORMED AND SETTLES OUT OF SOLUTION, THE PRECIPITATE. www.assignmentpoint.com
EXAMPLE/FORM EQUATION • AB + CD ----> AD + CB • THE CATIONS “TRADE” PLACES www.assignmentpoint.com
THE REACTION • WRITE THE BALANCED REACTION: • CaCl2(aq) + Na2CO3(aq) -----> 2NaCl(aq) + CaCO3(s) www.assignmentpoint.com
MATERIALS • RINGSTAND/WIRE TRIANGLE • FUNNEL • # 1 WHATMAN FILTER PAPER www.assignmentpoint.com
MATERIALS • ASSORTED BEAKERS • ASSORTED FLASKS • GLASS STIRRING ROD • DRYING OVEN www.assignmentpoint.com

PROCEDURE • ADD 1 GRAM OF EACH “SALT” TO 20 mL OF WATER IN TWO SEPARATE BEAKERS AND DISSOLVE, THEN MIX SOLUTIONS IN COMMON BEAKER www.assignmentpoint.com
PROCEDURE CONTINUED • POUR THE CONTENTS OF THE BEAKER THROUGH THE FILTER PAPER FUNNEL ASSEMBLY www.assignmentpoint.com
MORE PROCEDURE • REMEMBER, PRE-MASS THE DRY FILTER PAPER BEFORE FILTERING www.assignmentpoint.com
DATA AND CONCLUSIONS • CONSTRUCT A DATA TABLE • DESCRIBE WHY THE LAB RESULTS OCCURRED IN CONCLUSION • CALCULATE THEORETICAL YIELD, THEN PERCENT YIELD AND PERCENT ERROR www.assignmentpoint.com
