How does a base/ acid affect the speed in which ice melts?
If you use an acid to melt ice, then it will melt faster because it is has a lower pH than a base.
1. 5 plastic bowls(different colors help distinguish base and acid easy)
2. 1/4c. measuring cup
3. 1/3c. measuring cup
6. salt water(about 4tbs. salt added.)-acid
7. white vinegar(vinegar type doesn't matter)- acid
8. orange juice-acid
9. milk of magnesia-base
10. 2 eggs(beaten)-base
1. pour 1/3c. water in all five bowls and freeze thoroughly
2. remove bowls from freezer
3. add 1/4c. of each acid and base to seperate bowls
4. label each bowl according to the liquid added
5. time each bowls melting time
6. record on data chart
1. Orange Juice-87:35-acid
2. Salt water-92:28-acid
3. White Vinegar-94:08-acid
4. Milk of Magnesia-96:51-base
*Don't drink eggs, they are raw which could lead to sickness and do not drink milk of magnesia for it is medicine and is used for specific diagnosis.

2. amount of each liquid added

4. bowl material
1.liquid melting the ice
1. ice being melted
* Be sure to freeze the ice on a flat surface or ice will be slanted and will not evenly be covered and melted by substance.
Based on the data gathered in the experiment, the ice that melted with orange juice, which is an acid, melted faster only 87:35 mins/secs; where as the ice melted with eggs, which is a base, took 98:32 mins/secs. Accoring to this experiment my hypothesis was supported and an acid does melt ice faster then a base. My experiment could be more reliable if next time I had more trials to measure my responding variable. This experiment relates to a human problem because it can be used to melt ice on roads when they are iced over.
