Arrange the following compounds in order of increasing solubility in water: O2, LiCl, Ca(OH)2, methanol (CH3OH) an benzene (C6H6). Explain your answer.
Thank you so much it is ten percent of my final grade

1. CH3OH - solubility in water is unlimited
2. LiCl - it is ionic salt and ionic salts are often very soluble in water
3. Ca(OH)2 - it is slightly soluble in water (hydroxides of II.A group are not very soluble in water)
4. O2 - it is gas and under normal conditions it goes away
5. benzene - it's typical non-polar organic solvent and solubility of non-polar compounds in water is very low
sorry, it's in order of decreasing solubility :-)

Solubility of O2 is 7.6mg/L (20°C) and solubility od Ca(OH)2 is 176mg/L (20°C). Solubility depends on temperature in general... Thanks for discussion :-)...

I agree with the first answer with one exception. Are you given the temperature for the solutions? O2 will dissolve in water, fish and other water animals require it.As the temperature increases the amount of oxygen that will dissolve decreases.[Ca(OH)2 is very slightly soluble.]
