def
1-soln
mix of2or more sub to form homogenous molecular distribution
2-slightly sol electrode
slightly soluble but the soluble part compeletly ionized &conduct electricity
3-di_electric constant
solvent have the ability to separate to 2oppositly charged ions
4-hydrogen bond
force bet molecules containing higher electro negative atom &anthor one cotaining H atom
compare between saturated and super saturated soln(def_equilibrium)l
and write the reason of this variation in soln types??
-saturated sol :in which the dissolved solute is in equilibrium with the solid phase
-super saturated sol :sol which contains more of the dissolved solute than the saturation point
6-why polarity of glycerol more than polarity of acetone???
as di electric constant of glycerol =42.5
and the di electric const of aceton =2
and the higher the di electric constant the higher the polarity of the solvent
