I don't know your reference but you have a lot of info there. However, I think you need to relook at the solubility of citric acid in water. My reference says it is soluble and it has so many OH and COOH groups that I would expect it to be soluble in water, too.
I had to do the same exact lab...

Regarding your comment about citric acid, it seems that there may be a discrepancy in your information. While you mentioned that it is insoluble in water, my reference indicates that it is actually soluble. Citric acid contains multiple hydroxyl (OH) and carboxylic acid (COOH) groups, which are polar and tend to make it soluble in water.
