=Objective= To determine the solubility of salicylic acid in chloroform

=Procedure= In five .5 dram vials salicylic acid was placed. To each vial enough chloroform was added so that the salicylic acid was saturated. The vials were parafilmed and then placed in a water bath at 40C. After 58 minutes, a vial was quickly removed from the bath and then added to see if all the salicylic acid went into solution. After 58 minutes, the temperature was lowered to 25C.

=Discussions=

=Results= It was observed that it took the samples of salicylic acid to go completely into solution. At that time the temperature was lowered to 25C. =Conclusion=

=Log= 09-22-2009 16:00 - in five half dram vials, salicylic acid was placed. **[This is where you would name the vials - for example Vial141-1 to Vial141-5 That way to can refer to the vials later JCB]** To these vials enough chloroform was added so that the salicylic acid was saturated.**[you can't appraise saturation at this point JCB]** 16:07 – the 5 vials were placed in a heating bath at 40C **[At this point was there precipitate in any of the vials?]** 17:05 - the water bath temperature was lowered to 25C **[Include the measured temperature of the bath as well when you indicate that you change the setting JCB]** **[At this point was there precipitate in any of the vials?]**
