Benzoic acid synthesis
**4g Potassium Benzoate
**2mL water
**2mL *1.*5% HCl solution

The Potassium Benzoate was dissolved in warm water and HCl was added. Benzoic acid immediately precipitated out, and the solution was allowed to cool to room temp. The crude benzoic acid was collected via vacuum filtration, using the filtrate to complete the transfer and the filter cake was sucked fairly dry. The crude benzoic acid was dissolved in 3.5L of boiling water (a very little bit steam distilled creating very beautiful crystalline benzoic acid snow!), the vessel was insulated and allowed to slowly cool overnight. The solution was vacuum filtered, using the filtrate to complete the transfer, washed with ca. ******0mL water and sucked dry. The benzoic acid was dried at ******0F in an oven for about an hour.

The entire procedure was done 2x in parallel yielding ~**0g of benzoic acid.
