how the nature of solute and solvent affects solubility
Answers
Answer:
Strong solute-solvent attractions equate to greater solubility while weak solute-solvent attractions equate to lesser solubility. In turn, polar solutes tend to dissolve best in polar solvents while non-polar solutes tend to dissolve best in non-polar solvents.
Answer:
Nature of solute and solvent plays a vital role in solubility. phase ' Like dissolve like' refers to dissolving occurs when there is similarity between solute and solvent. Polar compounds soluble in polar solvent. Eg : Common salt is a polar compound and dissolve readily in polar solvent like water. Non polar compound soluble in non polar solvent. Eg: Fat dissolve in ether.
Effect of Temperature:
Solid in liquid :
The solubility of solid solute in liquid solvent increase with increase in temperature.
Gases in liquid :
Solubility of gas in liquid decrease with increase in temperature.
Effect of Pressure:
Effect of pressure is observed only in the case of solubility of gas in liquid . when pressure is increased the solubility of gas in liquid increases.
The common example for solubility of gas in liquid are carbonated beverage i.e soft drinks, house hold cleaners containing an aqueous solution of ammonia , formalin aqueous solution of formaldehyde, etc
