Describe a test that would distinguish between lactic acid and acrylic acid

pka of acrylic acid - 4.35
pka of lactic acid - 3.86
So put one in some water, test pH, throw the other in different water (same amounts) test pH, the one with the lower pH will be lactic acid.
Acrylic acid contains C=C so it should react with 0.05% KMnO4,while lactic acid will not.
Hope this helps.
