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

Comparing the solubilitys of copper sulphate, sodium chloride and potassium nitrate play down Information Molecular solids ( shekels) and bonce solids (salts) both unfreeze in irrigate system. However, they both send packing in divergent ways. The intermolecular forces holding molecules of scratch line together ar relatively fateon so when sugar is placed in piddle these bonds ar broken and individual C12H22O11 molecules be released into solution. It takes energy to break bonds among C12H22O11 molecules and it also takes energy to break the enthalpy bonds in water. These atomic number 1 bonds have to be disrupted in order to embark a sugar molecule into the substance. The energy needed for this is produced by the forming of bonds between slightly polar sucrose molecules and polar water molecules. This outgrowth works so well between sugar and water that up to 800g of sugar can break apart in 1 litre of water. The positive and negative ions in garret solids (or salts) are held together by the strong force of idolatry between particles with opposite charges. When a salt solves in water the ions are released and become associated with the polar termination molecules. Salts dissociate with their ions when they dissolve in water. H2O e.g.

NaCl (s) Na+ (aq) + Cl (aq) There are several factors that ordain affect solubility between unlike compounds: Temperature - If the solution process absorbs energy then the solubility spin up stakes be increased if there is a temperature increase. If the solution releases energy (exothermic, i.e. between sugar and water) then solubility will decrease. Molecular size of it - If t! he size or cargo of the individual molecules is large then solubility will be low because larger 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.
