Coke contains two acids: carbonic acid and phosphoric acid. A student titrates 10.0 mL of the decarbonated (removal of carbonic acid; can be achieved by gentle heating) coke with sodium hydroxide. If 36.7 mL of 0.0125 M sodium hydroxide is required to completely react with phosphoric acid in the coke, determine the amount (in grams) of phosphoric acid in 10.00 mL coke. (Include a balanced molecular equation in your answer and show all your calculations)

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...
