Iodine does not solve particulary well in polar solvents like water because it is not -and cannot form- one or more ions in solution.
The solubility increases much by the 'help' of 'co-soluted' iodide ions (I-) according to:
I- + I2 --> I3- (so-called Iodine-Iodide complex ions)

Can a non polar solute dissolve nonpolar solvent?
Yes, like dissolves like so a nonpolar solvent dissolves nonpolar solutes and polar solvents dissolve polar solutes
How can water dissolve ionic compounds and covelent compounds?
Water is a good solvent because it has polar -O-H groups and the same reason makes water a good solvent for polar compounds as acetic acid and hydrochloric acid. Water is not a good solvent for non polar compounds such as bromine and iodine.
Why does iodine do not dissolve in cyclohexane?
Iodine is soluble in cyclohexane. 'like' dissolves 'like' (i.e. non-polar dissolves non-polar) Iodine is non-polar as both atoms of iodine have the same electronegativities Cyclohexane is non-polar due to its symmetric structure Therefore iodine does dissolve in cyclohexane
What type of solvent is a polar solute most likely to dissolve in?
A polar solvent will most likely dissolve a polar solute. There be dipole-dipole attractive forces occurring between the two polar substances.
Is ethanol silver nitrate a polar solvent?
Ethanol is a polar solvent. Ethanol will dissolve silver nitrate.
Why is water a poor solvent for the recrystallisation of iodine?
Iodine is very soluble in water so therefore once it's dissolved, it won't crystallise. Good luck with your chemistry prac ;)
What does a polar solvent dissolve in?
a polar solvent dissolves a non polar solute
Which solutes dissolve?
It depends on the polarity of the solute and the solvent. If the solute is polar, then it will only dissolve in a polar solvent If the solute in nonpolar, then it will only dissolve in a nonpolar solvent
Why is Iodine more soluble in kerosene than water?
chemical make-up, In detail, The chemical reaction of the kerosene upon the iodine, It "shakes hands" and bonds with and therefore is more interactive allowing fluid reply.
Why iodine more soluble in potassium iodide than in water?
No. Iodine exist as I2, which is formed by the induced dipole-induced dipole interaction. Thus, it is a non-polar compound. Water, which is a polar solvent, prefers to stay hydrogen bonded then break up iodine. Remember: like dissolves like. This means that non-polar compounds like iodine will dissolve in non-polar solvent such as hexane, which polar compounds such as hydrochlorine gas will dissolve in polar solvents like water.
Can a non polar solute dissolve nonpolar solvent?
Yes, like dissolves like so a nonpolar solvent dissolves nonpolar solutes and polar solvents dissolve polar solutes
Which substance acts an solvent in tincture iodine?
Because iodine is nonpolar, a nonpolar substance like ethanol would dissolve it. Iodine is insoluble in polar substances like water.
How can water dissolve ionic compounds and covelent compounds?
Water is a good solvent because it has polar -O-H groups and the same reason makes water a good solvent for polar compounds as acetic acid and hydrochloric acid. Water is not a good solvent for non polar compounds such as bromine and iodine.
What type of solvent is best suited to dissolve ionic or highly polar substance?
The type of solvent that is best suited to dissolve an ionic or a highly polar solvent would also be highly polar, probably a polar protic solvent like water or alcohol.
Why does iodine do not dissolve in cyclohexane?
Iodine is soluble in cyclohexane. 'like' dissolves 'like' (i.e. non-polar dissolves non-polar) Iodine is non-polar as both atoms of iodine have the same electronegativities Cyclohexane is non-polar due to its symmetric structure Therefore iodine does dissolve in cyclohexane

Is ethanol silver nitrate a polar solvent?
Ethanol is a polar solvent. Ethanol will dissolve silver nitrate.
