How can the foam in the Elephant's Toothpaste reaction take 6 seconds…
How can the foam in the Elephant's Toothpaste reaction take 6 seconds to reach the top of a measuring cylinder?
Expense
-
More expensive chemicals
More potent chemicals: they will result in faster hypothesised reaction rate, but the expense of potent chemicals is higher priced than desired
Quality and reliability of chemicals: price of chemicals in comparison to their reliability, or quality. May take more money to retrieve chemicals with higher qualities
Safety
Safety equipment: use of fire-extinguishers expends money, as well as the purchasing of additional safety equipment to ensure safety
-
Hired safety staff: to supervise and ensure the safety of the experimenters, eg. the foam may catalyse quickly and could harm experimenters, which may cause fees to arise for hiring staff
-
-
Money saved
School has access to amounts of equipment that are both reliable and safe, which ensures a portion of expense saved
Personal expense, or at the school's
Chemical Reaction
Potential Factors
Concentration
Higher concentrations of hydrogen peroxide and chemical factors, leading to faster reaction, or increased rate of reaction
-
Temperature
Higher temperatures result in faster reaction time, as there is more kinetic energy of particles in the chemicals, which can lead to higher rates of reaction.
Lower temperatures result in slower rate of reaction, as the particles are colder and possess less kinetic energy to collide with particles, which results in lower rates of reaction
Catalyst
Speed of which the reaction is catalysed, depending on other factors such as the kind of catalyst, surface area, temperature.
State of catalyst; aqueous solution, solids. These states can affect how effective the catalysts are, as they reduced or increase the surface area in which the solution of hydrogen peroxide is catalysed
The ways in which the catalyst can be delivered into the hydrogen peroxide solution, it may be automated via a machine, or could be done via hands on experiment

-
Effervescence
-
Density of bubbles, leading to lots of foam
-
Food dye, for indication of reaction
-

-
-
-
Comparison between chemical endpoint and human determination of endpoint, eg. the chemical reactions that take place, that indicate the presence or significance of endpoint
Materials
The effect errors possess on the experiment: how they impact the results can the conclusions that can be made about the data at hand

-
-
How reliable is the data going to be, with the different materials
-
-
-
Storage
Decomposition of chemicals, may reduce the rate of reaction, which can reduce the theorectical 6 seconds
