A laboratory examination of double replacement reaction

1. DOUBLE REPLACEMENT

• A LABORATORY
EXAMINATION
OF DOUBLE
REPLACEMENT
REACTION

2. SAFETY

•GOGGLES
•HAIR TIED BACK
•APRONS

3. CHEMICAL THEORY

• THERE ARE MANY TYPES
DOUBLE REPLACEMENT
REACTIONS, SUCH AS ACIDBASE 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

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