Video Lab: Chemical reaction: Change in Color

- Опубліковано 23 сер 2024
- A chemical reaction-or chemical change-is the process by which some substances transform into others, changing their chemical composition and their chemical bonds.
Chemical changes can be detected because the physical and chemical properties of the substances involved in the reaction or reactants are different from the ones formed through the reaction or products.
A chemical reaction can be easily identified when it causes a change in a property of the substances involved that can be easily measured or detected: for example in the presence of caustic soda (NaOH) and water (H2O), potassium permanganate (KMnO4)-which is purple in color-reacts with sugar (C6H12O6) to form potassium manganate (K2MnO4)-which is green in color. As the reaction progresses, this new substance keeps reacting with sugar, forming manganese(IV) oxide (MnO2)-which is brown in color.
I’m definitely doing this for science fair.........😀
HELP, question:
I'm looking for a reaction where you start with color (any color is ok) and after a certain time, it becomes colorless. If possible I would like to do it with non-harmful chemicals, because it's going to be an experiment for primary school kids.
-Start with a color (already set up in the container, if possible use non-harmful chemicals or natural products)
-Add H2O and it becomes colorless
-If possible, change the time it takes to become colorless based on the concentration of the initial chemicals/products
-Use natural products or non-harmful chemicals, as it is an experiment for kids, primary school students.
Thank you very much.
Wow,Me ha encantado La forma en que va cambiando de color!
beautiful colour change
i am going to do this for the science fair with my friend s next week. i hope it works cuz if it doesnt am heart broken
Hi, do you mind telling me the amount of chemicals needed in this lab? I'm planning to do it in my chemistry class
Wow
you can send me procedure
😮😮😮😮
