The owner of a swimming pool supply company is offered what appears to be an exceptionally good deal on some concentrated muriatic acid. The solution is supposed to be 31.25% HCI by weight. The store owner has some suspicions about the seller and decides to have a sample analyzed before agreeing to make a purchase. You were hired to analyze the sample. You determined the density of the solution to be 1.367 g/mL. Then a 5.000- mL aliquot of the acid was diluted to 250.0 mL. A 50.00-mL aliquot of the diluted sample required 22.50 mL of 0.3000 M NaOH for titration to the phenolphthalein end point. (a) What is the weight percent HCI (FW-36.46 g/mol) in the original sample? (b) Based on the result, what should the store owner do?
