What color will gram positive cells become if you fail to use iodine?
Gram positive cells will appear pink if iodine is not used in the Gram staining process. This is because without iodine, the crystal violet stain is not retained by the thick peptidoglycan layer of the cell wall in Gram positive bacteria.
Why use iodine when preparing slide for viewing?
one disadvantage of using iodine to stain cells is that iodine will kill living cells.
What indicator chemical do you use to find sugar?

What is the chermical you test for starch?
Iodine solution is commonly used to test for the presence of starch. When iodine solution is added to a substance containing starch, the mixture turns blue-black in color, indicating the presence of starch.
What can YOU use to test if starch is present in our food?
You can use iodine solution to test for the presence of starch in food. When iodine comes into contact with starch, it changes color from brown to blue-black.
Diff between gram's iodine and iodine?
iodine& grams iodine Gram's iodine is a solution of 2% iodine and 3% potassium iodide in 70% ethanol. Gram's iodine is also used as a forensic toxicology reagent for the detection of alkaloids, as a source of iodine for iodometric titrations, as an indicator for the presence of starch, and as a general laboratory source of iodine/iodide. This solution is laboratory grade, and not for medicinal use. Iodine is non metallic,dark gray,lustrous,solid element

What is the use of Iodine in gram stains?
Iodine is used in Gram staining to form a complex with crystal violet, which helps to trap the dye within the cell wall of Gram-positive bacteria. This step is important in differentiating between Gram-positive and Gram-negative bacteria based on their ability to retain the crystal violet dye.
Why do you use iodine to stain a cell?
Iodine is used to stain cells because it binds to glycogen and starch, making them more visible under a microscope. This helps to visualize the cellular structures and identify specific components within the cell.
Why use saline in stool examination?
Saline is used in stool examination primarily to preserve the morphology and motility of parasites and other microorganisms. It helps to maintain the osmotic balance, preventing cells from bursting or shrinking, which aids in accurate identification under a microscope. Additionally, saline provides a clear medium that allows for better visualization of any pathogens present in the stool sample.

Can grams iodine be used before primary stain?
Probably not. The CVI complex formed between the iodine and crystal violet will be trapped in the lipid layer and not the peptidoglycan layer, so you would probably end up over decolorizing. This would cause a lot of false gram negatives. Probably not.

Does iodine kill gram positive and gram negative organisms?
Answer: yes. In his article "The End of Antibiotics and the Rise of Iodine as an Effective Alternative" Mark Sircus, OMD, says "Though it kills 90 percent of bacteria on the skin within 90 seconds, its use as an antibiotic has been ignored. Iodine exhibits activity against bacteria, molds, yeasts, protozoa, and many viruses; indeed, of all antiseptic preparations suitable for direct use on humans and animals and upon tissues, only iodine is capable of killing all classes of pathogens: gram-positive and gram-negative bacteria, mycobacteria, fungi, yeasts, viruses and protozoa. Most bacteria are killed within 15 to 30 seconds of contact." See the full article at
