This document provides instructions for writing a lab report on a double replacement reaction experiment involving calcium chloride and sodium carbonate. It outlines the key sections of a lab report such as an introduction, experimental procedure, results and data analysis, and conclusions. Safety precautions and materials needed are also listed. The purpose of the lab report is to inform the reader about the experiment and analyze the results in a clear, organized, and technical manner.

1. • A
LABORATORY
EXAMINATION
OF DOUBLE
REPLACEMEN
T REACTION

2. SAFETY
•GOGGLES
•HAIR TIED BACK
•APRONS

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

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

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

6. THE REACTION
• WRITE THE BALANCED REACTION:
•CaCl2(aq) + Na2CO3(aq)
-----> 2NaCl(aq) +
CaCO3(s)

7. MATERIALS
• RINGSTAND/WIRE
TRIANGLE
• FUNNEL
• # 1 WHATMAN FILTER
PAPER

8. MATERIALS
• ASSORTED BEAKERS
• ASSORTED FLASKS
• GLASS STIRRING ROD
• DRYING OVEN

9. REAGENTS
• Na2CO3 SODIUM
CARBONATE
• CaCl2 CALCIUM
CHLORIDE

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

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

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

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

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

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

16. 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

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

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

19. 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

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

21. 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

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