DOUBLE REPLACEMENT A LABORATORY EXAMINATION OF DOUBLE REPLACEMENT REACTION

SAFETY GOGGLES HAIR TIED BACK APRONS

CHEMICAL THEORY THERE ARE MANY TYPES DOUBLE REPLACEMENT REACTIONS, SUCH AS ACID- BASE NEUTRALIZATION AND PRECIPITATION.

PRECIPITATE REACTIONS THESE ARE REACTIONS IN WHICH AN INSOLUBLE SOLID IS FORMED AND SETTLES OUT OF SOLUTION, THE PRECIPITATE.

EXAMPLE/FORM EQUATION AB + CD ----> AD + CB THE CATIONS “TRADE” PLACES

THE REACTION WRITE THE BALANCED REACTION: CaCl 2(aq) + Na 2 CO 3(aq) -----> 2NaCl (aq) + CaCO 3(s)

MATERIALS RINGSTAND/WIRE TRIANGLE FUNNEL # 1 WHATMAN FILTER PAPER

MATERIALS ASSORTED BEAKERS ASSORTED FLASKS GLASS STIRRING ROD DRYING OVEN

REAGENTS Na 2 CO 3 SODIUM CARBONATE CaCl 2 CALCIUM CHLORIDE

PROCEDURE ADD 1 GRAM OF EACH “SALT” TO 20 mL OF WATER IN TWO SEPARATE BEAKERS AND DISSOLVE, THEN MIX SOLUTIONS IN COMMON BEAKER

PROCEDURE CONTINUED POUR THE CONTENTS OF THE BEAKER THROUGH THE FILTER PAPER FUNNEL ASSEMBLY

MORE PROCEDURE REMEMBER, PRE-MASS THE DRY FILTER PAPER BEFORE FILTERING

DATA AND CONCLUSIONS CONSTRUCT A DATA TABLE DESCRIBE WHY THE LAB RESULTS OCCURRED IN CONCLUSION CALCULATE THEORETICAL YIELD, THEN PERCENT YIELD AND PERCENT ERROR

TECHNICAL WRITING PORTFOLIO WRITING FOR A SPECIFIC PURPOSE NO FLOWERY PROSE, GET TO THE POINT MATH IS A LANGUAGE, CALCULATIONS ARE VITAL TO WRITEUP

PURPOSE WRITING TO INFORM, MAKE A DECISION OR LEARN HOW TO DO SOMETHING

AUDIENCE TARGET A SPECIFIC GROUP OUR GROUP IS MIXED AUDIENCE, IF YOU CAN WRITE DIRECTIONS TO PUT A SWING SET TOGETHER YOU CAN WRITE ANYTHING

ORGANIZATION WE WILL FOLLOW THE PROBLEM, CAUSE, SOLUTION FORMAT THIS LENDS ITSELF TO THE LABORATORY ORGANIZATION

WRITING CHOOSE THE DETAIL, AMOUNT OF DESCRIPITION GRAPHICS ENHANCE THE IMPACT OF A PAPER

COMPONENTS TITLE. TO THE POINT, DESCRIPTIVE OF THE LAB. INTRODUCTION. STATES CLEARLY THE QUESTION/PROBLEM AND WHY LAB WAS PERFORMED EXPERIMENTAL DETAILS/RESULTS : EXPLAINS WHAT YOU DID AND WHY, AND LISTS RESULTS

MORE COMPONENTS CONCLUSIONS & DISCUSSION ANALYZE THE RESULTS AND EXPLAIN WHAT HAPPENED IN THE LAB EXTENSIONS: “REAL WORLD” USES OF THIS REACTION AND LIME

STILL MORE COMPONENTS ACKNOWLEDGMENTS. LIST WHO CONTRIBUTED TO THE COMPLETION OF THE LAB REFERENCES. LIST ANY TEXTS OR MATERIAL USED IN THE WRITING OF YOUR PAPER

NUTS & BOLTS PAPER IN BLUE OR BLACK INK OR WORD PROCESSED FRONT OF PAPER ONLY TITLE PAGE DRAWINGS/ILLUSTRATIONS REQUIRED GOALPOSTS, GOALPOSTS, GOALPOSTS
