Iodine will dissociate from I2 into iodine ions in a polar solution. This explains why a mixture of alcohol and water can dissolve oil. The next two are pretty much doing the same thing in different ways. Some components of fresh or oxidised coal may wash out in water, kerosene or cooking oil but you will still have a handful of black material left that weighs almost as much as the starting material. Increasing temperature or stirring causes the molecules in the solution to move faster, colliding with the solute more often, increasing the probability that you can support the ionized form of iodine :). The sodium and chloride ions mix uniformly with the surrounding water molecules and thus salt dissolves in water, forming a homogenous (evenly distibuted) mixture. Determine the molar mass of an ideal gas B if 0.622 g sample of gas B occupies a volume of 300 mL at 35 °C and 1.038 atm.? When you place a non-polar molecule in a oil solvent like oil in water the molecules try to minimize surface contact between them. Cooking oils have a lot of water in them, and water will dissolve iodine. what is the product formed from a reaction between the two compounds. You can boil powdered coal in diluted nitric or hydrochloric acid and it will not dissolve though some of the sulphur and mineral content will. Why can sugar dissolve in cooking oil? This is soluble the basis for the cells in our bodies. Join Yahoo Answers and get 100 points today. Do radioactive elements cause water to heat up? The oils I am using are: Canola, Vegetable oil, Corn Oil, sunflower oil and olive oil. I'll briefly describe each since this is for your project :). Still have questions? Balance the equation I want to know why the Iodine dissolves in the oils and the reason that the longer it takes to dissolve, the more saturated it is. Why is the periodic table organized the way it is? The first one, saturated fats, are saturated for the fact that they do or dont have alkene bonds in the long carbon chains (if you ever wondered the difference between saturated or unsaturated fats thats your answer :) ). Scientists dissolve crude oil in water to study its composition. The first, volume, is pretty easy to understand because you have more solution in which you can pull apart those iodines and be able to keep them that way. At this point of a solutions saturation, you can not dissolve any more solute unless you do a few things: Increase volume, temperature, or stirring the solution. Get your answers by asking now. The second use of saturation is from the fact that when a solute has dissolved as much as it can in a solution then the solution is said to be saturated. Ni(s) + HCl(aq) → NiCl2(aq) + H2(g)     Magone/iStock/GettyImages Why Salt Does Not Dissolve in Oil You are using two different forms of the word in chemistry in your question. The time it takes to dissolve something is never really measured but the amount that can be … Hope that helped, best of luck on your experiment! Hi, for my science project, I am testing the saturated fat levels in different cooking oils by putting three drops of 2% Iodine in 20mL of each oil. The time it takes to dissolve something is never really measured but the amount that can be dissolved is. Ordinary soap such as diswashing liquid will emulsify cooking oil. Which leads me to your loose use of the term saturated. Solubility: The solubility of a solute in a particular solvent depends upon the solute-solvent interaction. Also, when water (polar molecules) fails to dissolve oil (nonpolar), it forms globules or visible particles of oil, signifying that they are immiscible. They will not, or will very weakly do this in a hydrophobic solution like oil, slightly meaning that you won't dissolve iodine in an oil. Write the coefficients going from left to right .? However, the amount of oil that will dissolve depends on whether there is more water or alcohol to the mixture. Cooking oils have a lot of water in them, and water will dissolve iodine.
