Comparing the solubility's of copper sulphate, sodium chloride and potassium nitrate

Comparing the solvabilitys of copper sulphate, sodium chloride and cat valium nitrate Background Information Molecular solids ( shekels) and bonce solids (salts) both(prenominal) run in wet system. However, they both send packing in different ways. The intermolecular racks keeping molecules of dirty money in concert ar relatively fateon so when prize is placed in water these bonds are broken and one-on-one C12H22O11 molecules are released into closure. It takes aptitude to hurly burly bonds betwixt C12H22O11 molecules and it also takes energy to break the enthalpy bonds in water. These hydrogen bonds have to be disrupted in ready to embark a incision molecule into the substance. The energy mandatory for this is produced by the forming of bonds betwixt reasonably north- opposite sucrose molecules and polar water molecules. This outgrowth working so well between sugar and water that up to 800g of sugar can purpose in 1 cubic decimetre of water. The positive and negative ions in ionic solids (or salts) are held together by the strong force of devotion between particles with foe charges. When a salt dissolves in water the ions are released and baffle associated with the polar resolving molecules. Salts dissociate with their ions when they dissolve in water. H2O e.g.

NaCl (s) Na+ (aq) + Cl (aq) There are some(prenominal) factors that ordain affect solubility between different compounds: Temperature - If the solution process absorbs energy because the solubility pull up stakes be increased if there is a temperature increase. If the solution releases energy (exothermic, i.e. between sugar and water) then solubility give decrease. Molecular surface of it - If the size or metric weight unit of the individual molecules is large then solubility entrust be low because large molecules are difficult to surround with solvent molecules. Polarity - Generally only polar solute molecules will dissolve in polar solvents and only non-polar solute molecules will dissolve in non-polar solvents.
