Purpose:
To investigate the relationship between the temperatures of Hydrochloric acid with the duration of Magnesium ribbon to dissolve in the acid.

Procedure: 1- Prepare four 400ml beaker: one for the hot bath, one for the room temperature, one for ice water bath and one for super hot bath. Fill all beakers half-full. Put one on a hot plate; the temperature of the water on the hot plate should not exceed 60C. Put another one on a hot plate; the temperature of water should not exceed 80C. Control the temperature of both hot plates to keep the temperature of water stays at 60C and 80C. 2- Using a graduated cylinder, add 20ml of 1M

10- Repeat steps 6 – 10 for hot water bath, ice water bath, and super hot bath. 11- Repeat steps 2 – 10 to collect a second set of data. 12- Average the reaction times at each temperature.

Data Analysis:

Temperatures | 1st set of data | 2nd set of data | | Temperature(Celsius) | Duration (Seconds) | Temperature(Celsius) | Duration(Seconds) | Room | 24 | 42 | 24 | 53:97 | Hot | 63 | 27:44 | 55 | 40:58 | Ice | 7 | 1:47:71 | 5 | 1:56:12 | Super Hot | 76 | 22:66 | 76 | 22:21 |

Temperatures | 1st set of data | 2nd set of data | | Temperature(Celsius) | Reaction rate(Seconds) | Temperature(Celsius) | Reaction rate(Seconds) | Room | 24 | 0.238 | 24 | 0.185 | Hot | 63 | 0.364 | 55 | 0.0246 | Ice | 7 | 0.6756 | 5 | 0.641 | Super Hot | 76 | 0.044 | 76 | 0.045 |

Conclusion:
We demonstrated that there’s a linear relationship exists between the temperature of hydrochloric acid and the duration of magnesium to dissolve in acid. As the temperature of the Hydrochloric acid increases, the duration for the magnesium to dissolve in the acid decreases.

Discussion of theory:
As the temperature of hydrochloric acid increases, the duration for the magnesium to dissolve in the acid decreases. Out data supports this concept, within reasonable margins of error. When the temperature of a solution rises, the energy of the particle of the solution also increases; making the particles move faster around each other. When the particles
