Water is a polar molecule (is a dipole, has a positive end and a negative end), hexane is a non-polar molecule. Like dissolves like. Water will dissolve other polar molecules, like HCl and NH3. Hexane will dissolve non-polar molecules like benzene or toluene.
Potassium nitrate is soluble in water, as it is an ionic solid. When dissolved in water, potassium nitrate will form an aqueous solution of potassium and nitrate ions.
If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.
Yes, hexane is hydrophobic as it can not make hydrogen bonds with water.
Potassium manganate 7 is more soluble in hexane than in water because it is a nonpolar solvent like hexane. Nonpolar solutes tend to dissolve better in nonpolar solvents, while water is a polar solvent. Therefore, the solubility of potassium manganate 7 is higher in hexane than in water.
No, it is an ionic compound which is soluble in water (a polar solvent) but not in Hexane ( a non polar solvent).
No, sodium chloride (NaCl) and hexane do not form a solution because they are immiscible. NaCl is a polar compound that dissolves in water, while hexane is a nonpolar solvent that does not interact with NaCl.
No, they would not form a solution.
Water and hexane are immiscible because they have different polarities - water is polar while hexane is nonpolar. This difference in polarity prevents them from mixing together to form a homogeneous solution.
Potassium nitrate is soluble in water, as it is an ionic solid. When dissolved in water, potassium nitrate will form an aqueous solution of potassium and nitrate ions.
water is a polar molecule, hexane is non polar. substances with like polarities mix, therefore the non polar iodine mixes with hexane and not water
Hexane is a nonpolar molecule and does not dissociate in water to form ions, so it does not have a pH value.
There are at least thousands if not millions of them, with hexane being a common example.
In a separatory funnel extraction with water and hexane, the hexane layer is the organic layer that is less dense than water and will be on top. Hexane is a nonpolar solvent, so it will preferentially extract nonpolar compounds from the mixture.
Hexane is a nonpolar solvent that helps extract nonpolar compounds, such as halogens, from an aqueous solution. By adding hexane, the halogens will preferentially dissolve in the nonpolar layer, allowing for easier separation and purification of the halogens from the aqueous solution.
Solubility is the property of a solute to dissolve in a solvent to form a homogeneous solution. The rule "like dissolves like" is used in terms of solubility. Urea is polar while hexane is non-polar, thus urea is not soluble in hexane.
Yes. If you put water and hexane in a beaker or a container together, the hexane will be on top of the water. One way to see this is to dye the water. They do not mix because water is polar and the hexane cannot dissolve in it. It is on top because, guess why? It is less dense than water. That is why anything floats on water... it is less dense! Hope that answers your question!
The observation in the reaction of hexane with bromine water is that the color of bromine water changes from orange to colorless as the bromine is being added to the hexane. This indicates that a reaction between hexane and bromine is taking place, forming a colorless product.
