From this result, can you assume this sample is indeed vinegar or contains some change? looks the san yes A chemical reaction occurred. A chemical reaction is a process where the atomsform new substances. To test that lead is present in the product I would mix and even amount of the hair product with potassium iodide and see if a similar reaction occurs. Chemical Of the two remaining one turns slightly yellow while one remains blue. The reaction turning yellow would be indicative of an acidic solution when mixed with BTB. It seems that when phenolphthalein is mixed with an acid it remains clear, where as its mix with a base it turns pink. 1. clear liquid T he sample turns pink.
