In chromatography how are the sunstances carried up the paper?
The solvent rises up the chromatography paper (blotting paper) by capillarity. When the solvent reaches the "spot" it dissolves the mixture of coloured chemicals. There is now a solution; this is a mixture of solutes dissolved in the solvent. The molecules of these different chemicals are all different sizes. The simple explanation is that the smallest solute molecules travel almost as quickly as the solvent molecules and so get carried to the top of the chromatogram. The largest solute molecules travel very slowly and stay near the bottom. So some of the coloured chemical travel further than others.
Why silica used in chromatography columns?
because silica is the best adsorbent used in column chromatography it almost supoort polar and non polar substances which areto be seprated....another reason is that it also seprate those substances which has intermediate polarities......
Why water isuniversal solvent?
Is isn't really. Well, it's referred to as such, but it's not really the universal solvent. Because not everything dissolves in it. So science lied to you. Welcome to the real world Jimmy. It happens. Go try to do some applied physics. Doesn't make much sense either. That's just how it is.

How does water get trapped in magma?
It really can't. If water touches magma, it almost instantly evaporates. Magma is far too hot to allow water to be a liquid for more than a few milliseconds. Magma is also one of thE hottest liquids in the world.

How does Chromatography works in Owls?
The solvent rises up the chromatography paper (blotting paper) by capillarity. When the solvent reaches the "spot" it dissolves the mixture of coloured chemicals.

The simple explanation is that the smallest solute molecules travel almost as quickly as the solvent molecules and so get carried to the top of the chromatogram. The largest solute molecules travel very slowly and stay near the bottom. So some of the coloured chemical travel further than others. If you are doing this with amino-acids you will not see anything happen until the end of the experiment when you stain it with ninhydrin.
Why does water called universal solvent?
Because it can absorb almost anything that can be absorbed.
What is the universal solvant?
water is called as the universal solvent because almost all the substances are soluble in water .so only we call water as the universal solvent .

What is a real world example of universal solvent?
yes water is a universal solvent as it has the property of dileteral constant which can almost break all covalent bonds as hence dissolves the matter into it

Is calcium chloride soluble in n-hexanol?
Calcium chloride is an ionic salt. n-hexanol is almost a non polar solvent. Therefore calcium chloride is slightly soluble in the given solvent.
