Transcript of The Sodium Iodine Clock

The Sodium Iodide Clock
Impact on Society
Relevant Scientific detail: Ingredients
Sodium iodide is an iodide salt that is formed into an injectable medicine.
Sodium sulfite: Soluble in water. Reacts with hot water, steam or acids to produce corrosive material
Citric acid is a common food additive and is found in everything from sodas to candies
citric acid
sodium iodate
Let's Get Started!
DISCOVERY!
Hans Heinrich Landolt
The Experiment Demonstrates:
This experiment demonstrates the idea of kinetics, the branch of chemistry or biochemistry concerned with measuring and studying the rates of reactions.
What is a sodium iodide clock?
Hans Heinrich Landolt

Discovered in 1886

Known for his humor, friendliness, puntuality, and cigar
The Sodium Iodide Clock shows how chemicals react to each other. This will benifit us in future medicine and scientific studies.
A chemical reaction
4 chemicals
sodium sulfide
sodium iodate
citric acid
a starch solution
Creates 2 solutions
When mixed, they create a solution that....
...changes color over time.
sodium sulfite
So......
It is called a clock reaction because the amount of time it takes to react can be changed by the amount of each ingredient put in.


Fun Fact: Although most people believe that only sugar can raise your blood sugar levels, starch can produce the same results.
...Why Call It A Clock?
