111 Experiment 11 AN INSTRUMENTAL ANALYSIS OF POP FOR ITS PHOSPHORIC ACID CONTENT The Pre-Lab . A student performs an experiment for the determination of phosphoric acid (H)PO present in a cola soft drink. A 0.5 milliliters sample of cola is diluted to 125 mL. The measured absorbance is 0.262. Using a graph of absorbance versus H,PO concentration, the student determines that the diluted cola solution has a concentra- tion of 15.5 x 10 moles liter: a) Calculate the total...
question 1 & 2 1. Magnesium solid reacts with aqueous hydrochloric acid to form the Mg2+ ion in solution. In an experiment, 60.0 mL of aqueous HCI was mixed with 0.1297 g of magnesium solid in a double Styrofoam cup calorimeter.
