difference between water of crystallization and interstiitial crystallization??

They probably are used for the same thing, but in the first, the water molecules are part of the crystal and found in repeated and regular levels.\n\nIn the interstitial, the water molecules may not be present in the same level in all the crystals and the level can not be predicted.

substances that have crystallization water trapped inside their molecules :D

Under normal curcumstances when water is cooled, it will form ice at its freezing point.  That is crystallisation takes place and an ice cube is formed.  If now the liquid is cooled past its freezing point without crystallisation taking place, a glassy substance is formed.\n\nWe can also cool saturated solution, without crystalllisation taking place to form a super saturated solution.  This is super cooling.

Water of crystallisation is the water which combines with the salt during crystal formation and gets attached to it and results in some very interesting properties of the crystal..\n\nIt depends on the nature f the salt, the temparature, the time of crystallisation, the catalysts and other factors.\n\nTry searching on google to get more info on water of crystallisation.

Ice takes up more volume than water, so the pressure is higher when you have the water in the freezer.  Crystals form at lower energies where entropy is lower, and higher pressure is equivalent to higher energy, so water remains a liquid.\n\nWhen you open it the pressure is released.  Gas expanding cools the air (entropy again) thus making the surface of the water lower in energy and promoting crystalization.  Poke a hole in the bottle and try this and the crystals will form in the freezer before you open it.

The solid phase.  Water is an exception.\nAlso some materials has more than one solid phase, such as carbon which has different structures and therefore different densities for graphic as opposed to diamond.

You need a variable in any experiment to compare results. Perhaps you could use cold (ice) water in one container, warm in another and hot or boiling in another. You can then make your prediction on which will dissolve first and have an experiment that will verify whether you have made an accurate prediction.

Crystallization occurs when an ionic compound (think table salt) which is dissolved in solution (think water)and the solvent(water) is subsequently evacuated. Table salt, or sodium chloride forms a crystal structure (like the granules you find in a salt shaker) in its solid state. The definition of a crystalline structure is characterized by a repetitive lattice-like pattern between the molecules. This salt example is not the only way crystallization occurs, but it's a good start.

By looking at it. A colloid has pieces that are large that will not mix in. A crystalloid has small pieces that will normall dissolve. Colloids are typically with liquids, and crystalloids, solids.

We can use water (H2O) to explain the difference between a compound and a molecule.\n\nWater, if you look at it on a macro level, is a COMPOUND, and this compound consists of many many (_illions) of water MOLECULEs (at the micro level) 'clumped' together. \n\nTo illustrate, take x to be a molecule of water. The box would represent the compound water.\n\n --------\n| xxxxx|\n --------

An alum solution with water makes a very nice crystal and is hydrated.  Check out this website with how to grow crystals: \n\nhttp://chemistry.about.com/cs/howtos/ht/alumcrystal.htm\n\nIn short, A hydrated crystal is a crystal that contains water as part of its chemical formula and structure. It may or may not absorb water vapor from the atmosphere. A crystal that is hygroscopic is one that absorbs water\nvapor from the atmosphere. CaCl2 and P2O5 are examples.

It is a method used to separate a solid organic substance from other solid impurities.\n-The impure solid is dissolved in a suitable hot solvent (to dissolve only the organic solid, not the impurites)\n-The impurities that did not dissolve in the solvent are removed by filtration.\n-The filtrate is left to cool, whereby any soluble impurities remain in the solution and the pure product crystallizes out.\n-The crystals formed are filtered using a vaccum filtration apparatus to help them to dry out quickly.\n-The crystals are washed with the cold solvent to remove impurities on the surface of the crystals.\n-Final drying of the crystals is carried out in a desicator at low pressure.

It would take exactly the same amount of time, once frozen there is little difference, between orange soda, and water. The sugar and CO2 in the soda, doesn't effect the time it takes for the frozen soda to melt, I have tried this in the lab, and the difference in the melt time is negligible. If you don't believe me, you will just have to do this experiment yourself.

the reaction is endothermic, so there is a slight decrease in the temperature of the water, as the system that consists of the dissolving tablet consumes heat from its surroundings.\n\nthe water gets colder.

Salt is a crystal......crystals grow when brought back to solid form

I'm sure this isn't the only material with this property.  \nDo you know what a phase diagram is?  If the line between the liquid and solid phases has a negative slope (goes down as you read it across) like the second phase diagram at this website: http://wine1.sb.fsu.edu/chm1045/notes/Forces/Phase/Forces06.htm\nAny material with a phase diagram that has the line between the liquid and solid phases as a negative slope becomes less dense (expands) when it freezes.  \nThe reason that water expands when it freezes is because when water crystallizes into ice, the structure leaves this pocket of emptyness in the middle of a ring of water molecules.  This makes the ice larger than the water it was when it was liquid.  Anything else that does this will also expand.

It has to do with the "activiation energy" involved in the process, increasing the stirring rate in a certain manner, increases the rate of collisions which increases the rate of reactions.  Solubility has to do with the free energy which are state functions with respect to temperature; the reactant and product states. Rates of reactions pertain more towards transitions states.
