Thermal Runaway Reactions Plan Paper

Thermal Runaway Reactions Plan
Hypothesis:
In this experiment, my hypothesis is that, the more concentrated acid there is, the bigger the temperature change in the experiment. This is because there are more acid particles to collide & react with each other.
Equipment:
* Beaker (100cm3) * Assorted measuring cylinders * Stopwatch * Thermometer * 0.1g of magnesium powder * 10cm3 of sulphuric acid
Method:
First, I will measure the correct amount of magnesium I need, which is 0.1g. Then I will measure out 10cm3 of the sulphuric acid into the measuring cylinder. Next, before I start the experiment, I will measure the starting temperature of the acid. Then I will place the magnesium and sulphuric acid in a beaker. I will measure the temperature every twenty seconds for three minutes and twenty seconds, and plot my results in a table. I will then re-do the experiment four times with a different concentration every time * 10 cm of acid; 0cm of water * 10cm of acid; 5cm of water * 10cm of acid; 10cm of water * 5cm of acid; 10cm of water
Risk Assessment: * Acid is irritant to skin, and hydrogen gas (flammable) is produced during the experiment. For my safety in the experiment, I will use the following safety procedures: * Wear safety goggles on at all times – This is to prevent acid going into my eyes. * Do not handle anything with my hands – If I handle acid with my hands, it could react to my skin or my clothes, and could burn my hands or skin. * Stand during the experiment – This is to prevent anything falling onto me and potentially harm me.
