Lab Report On Baking Soda And Vinegar
I. Introduction
Pressure is the application of force to a surface , and the concentration of that force in a given area . A finger can be pressed against a wall without making any lasting impression ; however , the same finger pushing a Thumbtack can easily damage the wall , even though the force applied is the same , because the point concentrates that force into a smaller area. Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas. Common units used to express volume include liters, cubic meters, gallons, milliliters, teaspoons and ounces. Many other units exist. The equation for baking soda and vinegar is CH3 COOH + Na HCO3 -> CH3 COONa + H2CO3 . This equation effects pressure and volume by rising the temperature and wanting to get out of the object. The researchers hypothesis is that when the volume decreases the temperature rises and the object inflates because it wants more space.

III. Procedures
1. First you bring the items you need; Baking soda, Vinegar, Zip lock bags, and String.
2. Then you get your items ready.
3. Then you insert some baking soda in a graduated beaker.
4. Then you insert 25mL of vinegar in the bag.
5. Then you insert 3 scoops of baking soda.
6. Then you mix them.
7. Then you observe.
8. Then write what you saw.
9. Then check the circumference of the bag if it didn’t pop.
10. Then start the next one.
11. First you insert 50mL of vinegar in the bag.
12. Then you insert 6 scoops of baking soda.
13. Then you mix them.
14. Then you observe.
15. Then write what you saw.
16. Then check the circumference of the bag if it didn’t pop.
17. Then start the next one.
18. First you insert 100mL of vinegar in the bag.
19. Then you insert 12 scoops of baking soda.
20. Then you mix them.
21. Then you observe.
