Is I2 aqueous?
Nearly insoluble in water but very soluble in aqueous solutions of iodides.
How do you make aqueous iodine solution?
Dissolve KI in about 20-30 ml of distilled water. Add iodine and heat gently with constant mixing until iodine is dissolved. Dilute to 100 ml with distilled water. Store in amber glass-stoppered bottle in the dark.
Is I2 a solid or iodine I?
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.
Is f2 a liquid?

What is aqueous iodine?
Lugol’s iodine, also known as aqueous iodine and strong iodine solution, is a solution of potassium iodide with iodine in water. It is a medication and disinfectant used for a number of purposes.
Is I and I2 the same?
Diamonds whose clarity is graded “I” have inclusions that are easy to see under 10x magnification. In addition, these stones usually have inclusions that are visible to the naked eye. I2 clarity: These diamonds will always have inclusions easily visible to the naked eye.
What is liquid fluorine?
Liquid fluorine is essentially 100 per cent pure, containing only traces of oxygen, nitrogen, and hydrogen fluoride. The liquid exhibits a clear yellow color, while the gas has a pale greenish-yellow color at ambient temperature. Fluorine is produced from a molten mixture of HF and KF by an electrolytic procedure.
Why is fluorine named fluorine?
The name fluorspar is derived from the Latin fluere, “to flow.” The mineral subsequently proved to be a source of the element, which was accordingly named fluorine.
