what are the steps to make a supersaturated solution?
544916
Heat the solvent, then it can take more solute into solution than when it's cool.  Then when you cool it, it is supersaturated.

you can only dilute it w/v as it is a solid. Just take 10gr and dissolve it in about 50ml distilled water, then make up to 100ml when it has cooled.

distill\n\nboil liquid, and cool the steam.

WEll... I was going to go to the trouble of giving you a real answer.   But since I see its already been answered I'll just say... \n\nDo it by trial... pour one milk jug of water into it at a time.\n\nYou could use milk too but that would be expensive and smell horrible

Assuming a pure substance, (this method will not work on mixtures).  \n1. Dissolve in Carbon disulphide.  (The compound is now banned in schools)\n2. Allow to evaporate in a fume cupboard.\n3. The presence of yellow rhombic like crystals is a test for S.\n4. Melt a sample and do a MP test.\n5. Melt a few grammes and allow to cool in air.  Needle like crystals will be formed.

I assume you know what osmosis is.\nIt would be nice to end up with enough results to plot a graph (LINE graph) so you will need at least four (more is better) solutions of different concentrations. Sucrose solution is usually used.\nUse a BIG potato so that all your samples are as similar as possible.\nThe easiest way to get uniform samples is to cut cylinders with a cork borer, then cut into 5mm disks.\nPut 10 discs into each solution.\nWeigh 10 discs before they are put in, then CAREFULLY blot them dry and reweigh them next day.\nCalculate the change in mass per gram of potato (you could expect some to gain, some to stay the same and some to lose so you will get some negative values).\nPlot a line graph of 'change in mass per gram of potato' AGAINST 'concentration of solution'.\nNow you must consider what the graph show you.

1) put them into the solution of bromine, the substance which makes the solution lose its colour is NaI\n2NaI + Br2 => 2NaBr + I2\n2) dissolve them in water, barium sulfate is the only one which cannot be dissolved in water\n3) Na2CO3 + 2HCl => 2NaCl + H2O + CO2\nNaHCO3 + HCl => NaCl + H2O + CO2

http://allergies.about.com/cs/treatment/a/aa040802a.htm\nA saline solution for irrigation is easy to make. To make an isotonic solution (one similar to the salt content of your bodily fluids), mix 1/4-teaspoon salt in an 8-ounce glass of warm water and add a pinch (1/4-tsp.) of baking soda. Discard any unused solution.\nYou may chose to use filtered or distilled water if your water contains a lot of chemicals. Table salt can be used, but many prefer to use non-iodized canning or pickling salt.\n\nIf you do not want to make your own solution, you can also purchase sterile saline at your local pharmacy or grocery store. You can find it in the contact lens care section of the store. The purchased solutions, however, do not contain baking soda. Using baking soda improves the mucus-solvent properties of the solution.\n\n\nhttp://www.flatrock.org.nz/topics/lifestyles/consumer_tips_for_salt_use.htm

Boil ¼ cup of water. Add one teaspoon of gelatin and one teaspoon of\nsugar. Stir for one minute until everything is dissolved.\n2. Cool the solution for ten minutes.\n3. Fill a petri dish to a little below the top edge.\n4. Close the petri dish by putting on the cover immediately. Let the\ncovered petri dish stand for at least four hours. Don’t touch the\ngrowth medium or you’ll add your own germs!\nThis recipe will fill two, small petri dishes. If you and your class plan to fill\nmore petri dishes, make more germ food by increasing the amount of your\ningredients proportionally.\n*Adapted from Gross But True Germs by Luann Colombo. See details in bibliography. If you don’t\nhave the materials needed for the experiment, you can purchase Ms. Colombo’s book, which includes\nall the supplies needed to conduct the experiment.

You know, I answered exactly the same question not 2 days ago.\n\nAnhydrous copper sulfate and water would be the easiest two. \n\nYou can buy copper sulfate at any good garden supply shop and most larger hardware stores. The copper sulfate usually sold is hydrated, and is already blue in colour.\n\nYou can make it anhydrous by putting it the oven, uncovered on a sheet of tin foil at 160oC or hotter. You will know when it has become anhydrous beause it goes white. This is quite safe to do in your kitchen oven, all you are doing is driving off the water. No nasty fumes or residues are produced.\n\nStore the crystals in an airtight jar to stop them absorbing water from the air. When you are ready add some water to a few crystals they will retrun to their original blue colour.\n\nThe other possibility is to manufacture your own cabbage indicator. That will make a bluish purple colour when mixed with baking soda. I've included a link with instruction on how to do this.

1/8 cup borax laundry detergent\n1 1/2 cup hot water\n1 cup white elmers school glue\n1 cup hot water \nMix borax with hot water. Stir until dissolved. Mix glue and water. put 1/2 cup plus 2 tablespoons of glue mixture in a medium Ziploc bag and add 2 drops food coloring. Add 1/4 cup borax mixture. Squish the bag to mix the ingredients well. Soon you'll have a slime. Put in small containers overnight. Children have a lot of fun playing with it and it's not messy

try to dissolve more sugar in it, if it doesn't work it's saturated.\n\ntake a drop of it out and put it on a surface, within 10 mins the water will evaporate leaving a sugar crystal the same size and shape as the water droplet.\n\nNot to scientific but useful all the same.

First, you dissolve your compound in the solvent in which is is most soluable (perhaps THF or methylene chloride).  Then you very carefully use a pipette to layer the solvent in which it is not soluable on top (perhaps diethyl ether or pentane).  You need to add the second solvent slowly and carefully.  Let the solvent run down the side of the container.  Obviously the top solvent needs to be less dense than the bottom one.  You then let the container sit undisturbed on the bench or in the freezer away from any vibrations until crystals form.  As the upper solvent diffuses into the lower solvent, you compound will become less soluable until it falls out.  The first solution should be as close to saturated as possible.

Fe(NH4)2(SO4)2 .6H2O is highly insoluble in non polar organic solvents like chloroform, dichloromethane, etc. Might be slightly soluble in alcohols. Better you dissolve it in minimum amount of water (make highly saturated solution) and add drop by drop alcohol  in a period of time and keep aside without shaking. Crystals will grow slowly.\nIt might be helpful.

Fill it with 42 Iorn BBs, run a wire from the metal bottom of the can to your speaker and push a coat hanger into the plastic lid so that it's touching the BBs, fill with a mixture of sodium chloride disolved in water.\n\nThat's how I'd do it anyway... perhaps the link below will help you more though.

Yes.  You can form a supersaturated solution with salt and boiling hot water in a glass jar.  Tie a pencil to one end of a string and a paperclip to the other.  Allow the pencil to rest on the top of the jar so the paperclip can hang in the solution, almost touching the bottom of the jar.  Allow the jar to sit undisturbed and you'll see crystals forming within 24 hours.

fill with liquid.  Pour out.  Do not clean.  Allow to dry.  Repeat until happy.
