What is the colour of iodine?
purple
Iodine is purple in a hydrocarbon solvent and yellowish-brown in water. The colour of the Iodine solution depends upon the nature of the solvent. Iodide ions are colourless, for example a solution of sodium iodide is colourless, and this solution will only be coloured if the positive ions were to be coloured.
What liquid iodine looks like?
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.
Can iodine exist as I?
Iodine on the periodic table. Iodine, with atomic symbol I, is a nonmetal that lies in group 17 of the periodic table, the halogens. Iodine lies below bromine, above astatine, to the right of tellurium, and to the left of xenon.
What color is the iodine solution normal?
A solution of iodine (I2) and potassium iodide (KI) in water has a light orange-brown color.
Which foods are high in iodine?
You can get recommended amounts of iodine by eating a variety of foods, including the following:
- Fish (such as cod and tuna), seaweed, shrimp, and other seafood, which are generally rich in iodine.
- Dairy products (such as milk, yogurt, and cheese), which are major sources of iodine in American diets.
What is the physical appearance of iodine?
Iodine is a nonmetallic , nearly black solid at room temperature and has a glittering crystalline appearance.
What is the structure of iodine?
Physical and chemical properties. Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states. Above 700 °C (1,300 °F), dissociation into iodine atoms becomes appreciable.
