�¬ À! Pressure changes only solubility of gases in liquids. The solute is, therefore, soluble in the solvent. Example: In 100 g water at 20 0C, 36 g salt can be dissolved. If molecular structures of solute and solvent are similar, more solute are dissolved in solvent with respect to solutions having dissimilar solute and solvent molecule structure. answer is there are many parameters affecting solubility, which make it impossible . An increase in temperature decreases both solubility and rate of solution.

Strong solute-solvent attractions equate to greater solubility while weak solute-solvent attractions equate to lesser solubility. Solubility can be expressed in precise or general terms. Solvent and types of solute, temperature, pressure and common ion effect are factors affecting solubility. In turn, polar solutes tend to dissolve best in polar solvents while non-polar solutes tend to dissolve best in non-polar solvents.

Solvent and types of solute, temperature, pressure and common ion effect are factors affecting solubility.

NaCl has one common ion with NaNO3 and 2 common ion with Na2SO4. \ Thus, if we add  5-3=2 g KCl it can also be dissolved in 20 g water. permission of www.ChemistryTutorials.org. The solubility of a molecule in water is measured in grams per liter. Lab Activity: soluble_or_insoluble_lab.pdf: File Size: 50 kb: There are two direct factors that affect solubility: temperature and pressure. This idea of solubility can be extended to the interactions between two liquids. Factors Affecting Solubility The common ion effect Consider the solubility of AgCl: AgCl(s) ⌦ Ag+(aq)+Cl(aq) in a solution that already has dissolved AgNO 3 in it. Effect of Pressure: It has been found that the gas solubility in liquids increases with increase in pressure. 2 1�h:p˜cœ °Ğ/ °à=!°"°#� $�ì%° °Ğ°Ğ�Ğ ‰ $$If –´ !v h5Ö I'#v I':V –l ”–Ö0ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ ÿ ÿ öI'ö 5Ö I'4Ö aö´ ytFp" ‰ $$If –´ !v h5Ö I'#v I':V –l ”tÖ0ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ ÿ ÿ öI'ö 5Ö I'4Ö aö´ ytFp" Œ $If K$L$–´ !v h5Ö Ç'#v Ç':V –l ”Ö0ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ ÿ ÿ öÇ'ö 5Ö Ç'4Ö aöH yth Œ $If K$L$–´ !v h5Ö Ç'#v Ç':V –l ”ZÖ0ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ ÿ ÿ öÇ'ö 5Ö Ç'4Ö aöH yth ‰ $$If –´ !v h5Ö I'#v I':V –l ”¸Ö0ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ ÿ ÿ öI'ö 5Ö I'4Ö aö´ ytFp" ‰ $$If –´ !v h5Ö I'#v I':V –l ”–Ö0ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ ÿ ÿ ö ö 5Ö I'4Ö aö´ ytáJ!
