Other methods for detecting fingerprints on a frame include using ninhydrin, cyanoacrylate fuming, or fluorescent powder. Ninhydrin reacts with amino acids in sweat to produce a purple color, cyanoacrylate fuming involves exposing the print to superglue fumes to create a white residue, and fluorescent powders can be used with a UV light to make the prints glow for easier visibility.

Which reacts to iodine glucose or starch?
Starch reacts to iodine to form a blue-black color, while glucose does not have a specific reaction with iodine. This is the basis of using iodine solution to detect the presence of starch in a substance.
Can we find yellow adulteration by chana dal and iodine solution?
No, you cannot find yellow adulteration by chana dal using iodine solution. Iodine solution is typically used to detect the presence of starch in food products. Yellow coloring in chana dal may be due to artificial coloring agents or other adulterants that may require different testing methods for detection.
What are other names for iodine?
Iodine is also known as I2 or iodide in its ionic form. It is sometimes referred to as molecular iodine.
What does iodine bond with?
Iodine typically forms bonds with elements like hydrogen, oxygen, and other halogens such as chlorine and fluorine. It commonly forms compounds such as hydrogen iodide (HI), iodine oxide (I2O5), chlorine iodide (ICl), and iodine pentafluoride (IF5).
Where to obtain iodine?
Iodine can be obtained from iodized salt, fish and other seafood, dairy products, and seaweed. It is also available as a dietary supplement in the form of potassium iodide or other iodine-containing compounds.
Is there a better technique to detect fingerprints other than iodine?
my head
What would be a better way to find fingerprints other than iodine?
You could use finger spray but don't use charcoal dust
Is there any better ways of showing fingerprints other than iodine?
i dont know, youy should ask Chuck Norris he'll know
Why does the solid iodine only stick to fingerprints when its heated?
because the iodine needs to make contact with the fingerprint so when it's a solid it can't do that. However when it is heated it turns in to gas (sublimation) it rises up and as it make contact with a coooler surface (the fingerprint) it crystallizes and makes it visable.
What regent would you add to starch agar plate to detect starch hydrolsis?
To detect starch hydrolysis on a starch agar plate, you can add iodine solution. Iodine reacts with starch to form a blue-black color, and if starch is hydrolyzed by the organism, the clear zone around the bacterial growth will indicate the presence of amylase, an enzyme that breaks down starch.
Which reacts to iodine glucose or starch?
Starch reacts to iodine to form a blue-black color, while glucose does not have a specific reaction with iodine. This is the basis of using iodine solution to detect the presence of starch in a substance.

Yellow coloring in chana dal may be due to artificial coloring agents or other adulterants that may require different testing methods for detection.
Do other mammals have fingerprints?
Yes only primates
How do you get potassium out of iodine?
You can't. Iodine is an element; no other substance can be extracted from it.
How does iodine differ from other halogens?
Iodine is solid and less reactive.
Do koalas and humans have unique fingerprints?
Not really. While koalas are the only known animal to have distinctive fingerprints, they can be distinguished from the fingerprints of a human. Like humans, their fingerprints comprise ridges in a variety of patterns.
Are koalas' fingerprints like ours?
Yes and no. According to the Australian Koala Foundation, koalas have fingerprints that are very distinct from each other, just as humans do. However, they are easily discernible from human fingerprints.
