How do you prepare 0.02N iodine solution?
To prepare a 0.02N iodine solution, you would need to weigh out the appropriate amount of iodine (I2) and dissolve it in a solvent, such as distilled water or an alcohol like ethanol, to make the desired volume, typically 1 liter. The exact weight of iodine needed would depend on the molar mass of iodine (253.8 g/mol) and the desired normality (0.02N). Make sure to wear appropriate personal protective equipment and handle iodine carefully, as it is toxic and can cause skin irritation.
How do you prepare 0.1 Normality of iodine solution?
To prepare 0.1 Normal iodine solution, you would need to dissolve 12.7 grams of iodine in 1 liter of a solvent such as water and then adjust the volume accordingly. This solution can be standardized using a thiosulfate solution to verify the normality.
Why is A crystal of iodine on heating in a closed flask turn into vapour and fills the complete flask?
Iodine sublimes directly from a solid to a gas when heated, without passing through a liquid phase. In a closed flask, the vaporized iodine molecules are unable to escape, so they accumulate and fill the entire volume of the flask. This process is known as sublimation.
What is the common name for iodine?
The common name for iodine is iodine.
What does l mean in chemistry?
The "I" in chemistry probably refers to the element iodine.
How do you prepare 0.1M IODINE?
2grm iodine and 4grm KI add to 1000ml of water
What is the composition of 2percent iodine tincture?
Active Ingredient: Iodine 2% Ingredients: Alcohol 47% by volume, Deionized water, and Sodium iodine 2.4% Although this doesn't seem to add up to 100%, this is what the label says.
Preparation of 0.1n iodine solution?
According to Kodak: For a 0.1 Normal (0.1N) solution of iodine (I2), in 1 L volume flask, dissolve 40 g potassium iodide in 25 mL water. Next, add 12.7 g iodine (I2) and dilute to 1 L. Note that a 0.1N solution is not the same as a 0.1M solution. For iodine 0.1N is 0.05M.

how do calculated normality of iodine?
To calculate the normality of iodine, first determine its equivalent weight based on the reaction it participates in, typically involving redox reactions where iodine can act as an oxidizing agent. Normality is then calculated using the formula: Normality (N) = (grams of solute / equivalent weight) / volume of solution in liters. For iodine, if you know the concentration in grams per liter and the equivalent weight, you can directly compute its normality.

How much iodine is an overdose?
On average (and each person is slightly different) anything over 1,100 micrograms, total, can be considered an overdose. This includes the iodine that you get from food. 1,100 micrograms is the same as 1.1 milligrams. A full gram of water, say, occupies a volume about the same as a sugar cube. So it takes very, very little pure iodine in you to be an overdose. Yet, you cannot live normally without a tiny bit of iodine in your body. That is why table salt comes with a tiny amount of iodine in it.
What is the solution of tincture of iodine?
iodine
What is the procedure for the standardization of sodium thiosulfate?
Thiosulfate can be standardised by adding excess potassium iodide solution to a known volume of a standard acidified solution of potassium dichromate, and then titrating the liberated iodine against the sodium thiosulfate solution.http://www.meduniv.lviv.ua/files/kafedry/tokshim/English/Analytical/Manuals_Analytchem/Iodometry.pdf
