The iodine clock reaction is a favorite demonstration reaction in chemistry classes that usually requires toxic or hazardous chemicals. During the reaction, two clear liquids are mixed, resulting in another clear liquid. After some time, the solution suddenly turns dark blue. The reaction is called a clockreaction because the amount of time that el...
Determine how the concentration of hydrogen peroxide affects the rate of the iodine clock reaction and determine the reaction order.
Chemical kinetics is the branch of chemistry that is concerned with the mechanisms and rates of chemical reactions. The mechanism of a chemical reaction is a description of what happens to each molecule at a very detailed level—which bonds are broken, which new bonds are formed, and how the three-dimensional shapes of the chemicals change during th...

It all has to do with a concept called miscibility and another important factor called density. Miscibility describes how well or how easily two liquids mix together. Some liquids, like orange juice and water, mix together easily and become a special kind of mixture called a homogeneous mixture.
Mar 4, 2024 · Chemistry Science Fair Projects. All of these chemistry experiments are perfect for using the scientific method. Form a hypothesis, alter the variables, and then observe the results! You can simplify these projects for younger kids, or add more complexity for older students.
Dissolve coloured sweets to create a rainbow. 20 October 2024By Declan Fleming. Demonstrate diffusion, density and the particle model to your 14–16 learners in this easy experiment.
Jan 2, 2023 · This science experiment lab is supporting the concepts of osmosis, equilibrium, solutions, solutes, and solvents. A solution is a homogenous mixture of one or more substances. The parts that are mixed to achieve a solution are called the solute and the solvents.
