Evaporation:it is used to separate dissolved solid particles from a liquid in a solid-liquid mixture as in a solution.when a solution is heated,the liquid or solvent in the solution evaporates,i.e.becomes vapour,leaving behind the dissolved solids as residue.\nFiltration:filteration is used to separate insoluble olids from the liquid in solid-liquid mixture as in a suspension.in the process of filtration,insoluble solid particles are trappedinn the filter as residue while the liquid pases through the filter and is collected as filtrate.\nDistillation:it is used to separate a solvent from  a solution.In the process,the solution is heated so that its liquid component evaporates and escapes as vapour.the vapour is then cooled and condesed into liquid called the distillate.it is widely used in the perfume industry.if more than one liquid component in a mixture of liquids need to be separated,fractional distillation is used.\ni only know this hope it works......best of luck.

A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask. It is done by using the principles of the kinetic theory of matter.\nAnother cool project might be doing something with dry ice. Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions. Make some dye molecules or something.\n\nHope one of these ideas works for you.

is this your school homework,  are there suppossed to be other questions before these because my computer shows them starting from No. 4.\nnway,\n4.  filter the solution while still hot because as the soltion cools crystallization occurs, and you will nloose your product on the fiolter paper.\n5. crystallization can be induced by reduction in temperature i.e put in an ice bath or you can use a technique called seeding where you put a few crystals of the expected substance in the solution, the other method is to increase the concentration of the solution by evaporating it, to saturation point, ensure you do not evaporate it dry.\n6.i do not know what you started with so i can not tell.\n7.slow cooling will definately give bigger crystalls.\n8.sodium chloride reacts with silver nitrate to form a white precipitate, actually silver nitrate solution is used to analyse NaCl in industrial setting.\n\nope you will find these information sufficient.

Here's an interesting experiment.

I'm going to assume you mean water distillation.  Water distillation is done by evaporating water (one change of state: evaporation), and then cooling that water vapor (another change of state) and collecting the liquid water.

Yeah, that's a good suggestion.  \nYou might also want to try stirring with a bulbous glass stirring rod or a rubber policeman very carefully.  Also, I think you'd be okay if you stir without making contact with the paper.  Perhaps the best suggestion, though, would be to pull through a little bit of your sample at a time; that way, your filter can handle pulling almost all of the liquid out of a small sample, then you add more in, etc., until it's all in and dry.

It would depend on what the nature is of the unwanted impurities. One could use chemical separation or distillation.  Distillation would be the easiest.

Specifically: water, pyridine, squalene, urea, acetic acid, lactic acid, complex alcohols and glycols, ketones, and aldehydes.

basically you're talking about distilling water, which is a purification technique.  collect the water vapor and let it condense. the result is pure water.

its either desalnation or distillation

vinegar and baking soda. \nWill also be fun experiment for them!

See comment above.\n\nYou do need to do several trials at various concentrations though. You can then determine it through a linear regression.\n\nI also suggest that you consult a book on Analytical chemistry, because Beer's law has limitations. For example, it loses linearity at higher concentrations.

There are lots of other hygrometer techniques. \n\n1. Conductivity\n2. IR absorption\n3. electrolytic method\n4. hair hygrometers (hair curls when it is moist, as everyone knows)\n\nAnd so on.

One that will ideally:\n1) dissolve the component that you wish to collect but not the others. Then you can do a filtration, collect the filtrate and evaporate off the solvent to get back the component that you want.\nOR\n2) dissolve all those that you don't wish to collect but not the component that you want. Then you can do a filtration and collect the component that you want as the residue.\n\nHope this helps :)

Here's some ideas\n\n(1)\nMeasure the hardness and ion content of your local water supply.  You can perform precipitation experiments, measure solid residue after evaporation, and more.\n\n(2)\nSeparate the protein solids and fat from milk.  I think you can do this by adding salt to the milk.  (I've never done it, may be too easy.)\n\n(3)\nDo a project on the danger of confined spaces.  There is a really cool visual experiment that goes along with this.  If you mix vinegar and baking soda in a tall glass you will get a glass full of carbon dioxide.  Since the carbon dioxide is heavier than air, it will stay in the glass for a while (invisibly so).  You can then make a "pouring action" and pour the CO2 into a second glass, although there is no visible flow of gas.  You also need a 3rd glass that has a small, lit candle at the bottom of the glass.  You then make the same pouring action with the second glass into the third and when the CO2 displaces the oxygen and nitrogen in the third glass the candle will get snuffed out.  You can even do this experiment at home for fun!\n\n(4)\nMeasure the pH of common household materials: foods, cleaners, etc.
