AdministratorHow does BZ reaction work?
The Belousov-Zhabotinsky (BZ) reaction is a family of oscillating chemical reactions. During these reactions, transition-metal ions catalyze oxidation of various, usually organic, reductants by bromic acid in acidic water solution. Most BZ reactions are homogeneous.
How do you do the Belousov-zhabotinsky reaction?
Procedure
- In a 1 liter flask, add 300ml solution A to 300ml solution B.
- Wait until the solution clears, add 300ml solution C, mixture turns orange with the smell of bromine.
- Wait until the orange color fades to the yellow cerium solution color and add 3.6ml solution D.
What are the products of baking soda and vinegar?
The reaction of sodium bicarbonate (baking soda) and acetic acid (vinegar) produces carbon dioxide gas, water and sodium acetate (soluble in water).
Does luminol glow in the dark?
Luminol (C8H7N3O2) is a chemical that exhibits chemiluminescence, with a blue glow, when mixed with an appropriate oxidizing agent.
How long does the Briggs Rauscher reaction work?
about 3-5 minutes
The reaction begins when three colorless solutions are mixed together. The color of the resulting mixture will oscillate between clear, amber, and deep blue for about 3-5 minutes. The solution ends up as a blue-black mixture.
Why does the Briggs Rauscher reaction stop?
The concentration of iodine decreases, and so the dark-blue solution with starch stops forming.
How long does the Briggs Rauscher reaction last?
about 5 min
Three colorless solutions are combined into a large beaker and the mixture becomes amber, then blue-black, and then colorless again. This sequence of color changes will repeat with a period of approximately 15 seconds at 25 oC. The reaction last about 5 min.
What happens when you mix baking soda and vinegar chemical reaction?
Mixing baking soda (sodium bicarbonate) and vinegar (acetic acid) causes a chemical reaction that produces a salt (sodium acetate) and water, as well as carbon dioxide gas.
What type of reaction is the reaction of baking soda and vinegar?
A chemical reaction is a process in which substances undergo a chemical change to form a different substance. Mixing baking soda and vinegar will create a chemical reaction because one is an acid and the other a base.
Can you make luminol at home?
(Ref 1) You can buy luminol, but you can also make it on your own. Mix the luminol powder and washing soda together as a dry mixture in a bowl. Stir in the distilled water a little at a time. Add the hydrogen peroxide to the mixture in the bowl a little at a time.
