Nearly insoluble in water but very soluble in aqueous solutions of iodides. BLUISH BLACK OR DARK PURPLE CRYSTALS WITH PUNGENT ODOUR.
Is i2 aqueous?

Is I2 solid or aqueous?
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.
Is iodine a gas or aqueous?
As a pure element, iodine is a lustrous purple-black nonmetal that is solid under standard conditions. It sublimes (changes from a solid to a gaseous state while bypassing a liquid form) easily and gives off a purple vapor.
Does I2 exist in liquid state?
Iodine, for example, at ordinary pressures can exist in the liquid state at temperatures in the interval from 113.6 to 184.4 °C (Petrucci, 2001).
Is iodide soluble in water?
Most iodide salts are soluble in water, but often less so than the related chlorides and bromides. Iodide, being large, is less hydrophilic compared to the smaller anions. One consequence of this is that sodium iodide is highly soluble in acetone, whereas sodium chloride is not.
What kind of solid is I2?
Iodine (I2) consists of larger, nonpolar molecules and forms a molecular solid that melts at 114 °C.
Can I2 be solid?
Despite intermolecular forces being a weak individual force of attraction, collectively they are very strong and the numerous forces between iodine molecules means that more heat energy is required to break these intermolecular forces and separate the molecules therefore iodine is a solid.
Is I2 soluble in benzene?
Solubility: the solubility of iodine, expressed in g/kg of solvent at 25 °C is: H2O, 0.34; benzene, 164.0; CCl4, 19.2; CHCl3, 49.7; ethyl acetate, 157; ethanol, 271.7; diethyl ether, 337.3; n-hexane, 13.2; toluene, 1875.
Is I2 solid at room temperature?
Iodine exists as a solid at room temperature because the strength of these forces are in line with iodine’s large electron cloud and polarizability.
What is the chemical name for I2?
Iodine | I2 – PubChem.
Is silicon a solid liquid or gas?
Silicon is a chemical element with symbol Si and atomic number 14. Classified as a metalloid, Silicon is a solid at room temperature.
Why I2 is solid and cl2 is gas?
Explanation: Iodine is present in solid form at room temperature while chlorine is a gas at room temperature because of the difference in intermolecular forces that act on between individual molecules. Iodine has atomic number 53 while chlorine has 17, so iodine has more electrons in its electron shells.
Why is I2 not soluble in water?
Iodine does not dissolve in water because water is an extremely polar molecule, while iodine exists in the diatomic form of I2, and is therefore non-polar, and will not dissolve in water. It is a non-polar molecule because the carbon-hydrogen bond has a small electronegativity difference of around 0.4.
Is Ki I2 a mixture?
The potassium iodide and the iodine that reacts with it increase the density of the phase. The solutions form a heterogeneous mixture.
Is I2 polar or nonpolar?
Iodine (I2) is a nonpolar molecule as it is a diatomic molecule and is symmetric in shape ie; linear. Both Iodine atoms share an equal proportion of charge and have equal electronegativity due to which the net dipole moment of the I2 molecule comes out to be zero making it a nonpolar molecule.
