What is the purpose of using starch indicator solution in a chemical reaction?
The purpose of using starch indicator solution in a chemical reaction is to detect the presence of iodine, which can indicate the completion of the reaction or the presence of specific substances.
What is the purpose of using iodine flasks in chemical experiments?
Iodine flasks are used in chemical experiments to safely contain and mix chemicals, particularly those involving iodine solutions. They help prevent spills and ensure accurate measurements and reactions.
Who to calculated normality of iodine?
Normality of iodine ((I_2)) can be calculated using the formula: Normality = Molarity x n, where n is the oxidation state of iodine in the reaction. For example, if you are using a 0.1 M (I_2) solution in a redox reaction where iodine is being reduced to iodide ions ((I^-)), then the normality of iodine would be 0.1 N.
How would you separate iodine crystals from mixture of iodine and sand?
One method to separate iodine crystals from a mixture of iodine and sand is by using sublimation. Heat the mixture, and the iodine will sublimate (turn into gas) leaving the sand behind. The iodine gas can then be collected and cooled to form iodine crystals.
Is there a method for detecting starch without using iodine?
Yes, you can detect starch using enzymes like amylase to break down the starch into simpler sugars, and then test for the presence of those sugars using a glucose test strip or a colorimetric assay. This method is often used in laboratories as an alternative to iodine staining.
Is Gentian Violet good to use for canker sores on your tongue?
Gentian violet can be effective for treating canker sores due to its antifungal and antiseptic properties, which may help reduce pain and promote healing. However, it can also cause staining and may irritate sensitive tissues. It's important to consult with a healthcare professional before using gentian violet, especially for oral conditions, to ensure it's appropriate for your situation and to discuss potential side effects.
How does gentian violet come off skin?
Gentian violet can be removed from the skin using rubbing alcohol or isopropyl alcohol, which helps dissolve the dye. Alternatively, applying a mixture of soap and warm water can also be effective; gently scrubbing the area may aid in lifting the stain. If the stain persists, using a commercial stain remover or a paste of baking soda and water can help. Always test any product on a small area first to avoid skin irritation.
What happens if grams iodine is not applied after staining with crystal violet?
If the iodine in the Gram's stain was omitted, the crystal violet which enters the cell will not be able to form the Crystal Violet Iodine (CVI) complex. The CVI complex molecule has a larger size than that of Crystal violet molecule and hence Gram +ve bacteria are able to retain the stain. If iodine were omitted, even Gram+ve cells would get decolorised by Alcohol treatment and would be seen as Gram-ve cells.

What was the purpose of using iodine?
Iodine is commonly used in medical applications as an antiseptic to disinfect wounds and prevent infections. It is also used in the production of thyroid hormones to support metabolism and regulate growth and development.
What do the particles look like in gas?
At the molecular level iodine gas contains I2 molecules, which if you could see them ( they are too small to be seen using light) and you were able to see the electron density then they would appear as small dumbells. When iodine sublimes the colour of the "gas" is violet this due to the aborption of visible light by the I2 molecule.
Why use iodine when preparing slide for viewing?
one disadvantage of using iodine to stain cells is that iodine will kill living cells.
What are the nutritional benefits of iodine?
Iodine is very useful for our body. Iodine deficiency can cause thyroid. So just check your iodine level in your salt which you are using in your food. Better use Iodine Salt.
Why does iodine work when using to find fingerprints?
probably because iodine sticks to the oil from your fingers
What is the gland doctors image with iodine-131?
The thyroid gland is often imaged using a salt of iodine-131 as this gland has a high uptake of iodine.
