Vinegar is an aqueous solution of acetic acid. By law, it must contain 4 g acetic acid per 100 ml solution. What approximate volume of 0.10 M of NaOH would be neededto titrate a 15.00 ml aliquot of commercially availabe vinegar? If the aliquot required 5.28 ml to reach the end point, does the sample contain at least 4 g of acetic acid per 100 ml solution?
