Because it didn't react with the iodine, i don't know
What else can I help you with?
Why did the the mixture stop turning the drops of iodine solution blue after 240 s?
The mixture stopped turning the drops of iodine solution blue after 240 seconds due to the completion of the reaction between iodine and the other components in the mixture. Once all the iodine had reacted, there was no more available iodine to cause the blue color change.
Why was the mixture stop turning the drops of iodine solution blue after 240 s?
The reaction between iodine and starch forms a blue-black complex. Once all the starch present in the solution has reacted with the iodine, no more blue color will be observed. This explains why the mixture stopped turning the drops of iodine solution blue after 240 seconds.
Why did the mixture stop turning the drops of iodine solution blue after 240 seconds?
The reaction between iodine and starch is complete after a certain period of time, typically around 2-4 minutes. Once all the available starch molecules have formed a complex with iodine, there are no more free starch molecules for the iodine to react with, resulting in the iodine solution no longer turning blue.
Why does a mixture of enzyme stop turning the drops of iodine soloution?
When a mixture of enzymes stops turning drops of iodine solution, it is likely because the enzyme has catalyzed the reaction that converts starch into glucose, which iodine detects by changing from a blue-black color to a brown or yellow color. Once all the starch has been broken down into glucose, there is no longer any substrate for the iodine to react with, so it remains in its original blue-black color.
Which substance turns a blue-black colour when treated with a few drops of iodine solution?
Starch turns a blue-black color when treated with a few drops of iodine solution. This color change occurs due to the formation of a complex between the starch molecules and the iodine ions.

What is the food test that remains brown after 2 drops of iodine solution?
The food test that remains brown after 2 drops of iodine solution typically indicates the absence of starch. Iodine solution turns blue-black in the presence of starch, so if it remains brown, it suggests that the tested food does not contain significant amounts of starch, possibly indicating the presence of sugars or proteins instead.
How can one effectively test iodine?
To effectively test iodine, one can use a starch test. This involves adding a few drops of iodine solution to a sample and observing if a blue-black color appears, indicating the presence of iodine.
If you put a few drops of iodine solution on a potato slice?
The iodine solution will turn dark blue or black in the presence of starch in the potato slice. This is because iodine reacts with starch, forming a blue-black complex. It's a common test for the presence of starch in foods.
How do you test for starch in a seed?
You can test for starch in a seed by using iodine solution. Add a few drops of iodine solution to the seed and observe for any color change. A blue-black color indicates the presence of starch in the seed.
Which color is given by glycogen on reaction with iodine?
reddish-brown * the color of glycogen solution with drops of NaCl and Iodine solution is Dark Orange. :) *NaCl will intensify the colour as it fulfills the optimum ionic requirement of the reaction
What happened when a few drops of CCl4 was added to aqueous I2 with starch?
When a few drops of carbon tetrachloride (CCl4) are added to an aqueous solution of iodine (I2) mixed with starch, the iodine dissolves preferentially in the organic layer of CCl4 rather than remaining in the aqueous phase. This causes a color change; the starch-iodine complex in the aqueous layer, which typically appears blue, will lose its color as iodine moves into the CCl4 layer. The result is a clear separation of phases, with the CCl4 layer turning reddish-brown due to the dissolved iodine, while the aqueous layer becomes lighter in color.
