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

Comparing the solubilitys of copper sulphate, sodium chloride and potassium nitrate telescope Information Molecular solids ( shekels) and bonce solids (salts) both unfreeze in weewee system. However, they both send packing in assorted ways. The intermolecular forces holding molecules of starting line together ar relatively fateon so when sugar is placed in weewee these bonds ar broken and individual C12H22O11 molecules be released into solution. It takes energy to break bonds betwixt C12H22O11 molecules and it also takes energy to break the enthalpy bonds in water. These hydrogen 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 up in 1 litre of water. The positive and negative ions in loft solids (or salts) are held together by the strong force of cultism between particles with opposite charges. When a salt send aways in water the ions are released and become associated with the polar root 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 divergent compounds: Temperature - If the solution process absorbs energy then the solubility gain 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 the size or cant of the individual molecul es is large then solubility will be low beca! use 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.
