diprotic acid. The procedure for identifying an unknown acid is exactly as described in the lab manual. Part 1: Standardization of NaOH. 1.4378 g of oxalic acid was dissolved in 250.0 mL of water and a 25.00 m aliquote was titrated with NaOH. 24.73 mL of titrant was required. Determine the concentration of sodium hydroxide. Answer: Part 2: Titration of the unknown acid. 1.9875 g of the unknown acid was dissolved in 250.0 ml of water and 25.00 ml of this solution was titrated with the NaOH. 29.50 mL of titrant was required. Determine the Molar Mass of the unknown. Answer:

Determine the Molar Mass of the unknown. on Answer:
Identify the unknown acid from the following choices: Succinic Acid COOH(CH2)2COOH Oxalic Acid (COOH)2.2H,O Adipic Acid COOH(CH2)4COOH Potassium Hydrogen Phthalate COOHC,H,COOK Sulfamic Acid NH2SO;H Citric Acid COOHCH,C(OH)(COOH)CH;COOH HINT: COOH represents a carboxylic acid group. Each time you see this qgroup in a molecular formula it contributes one acidic proton. O a. Adipic Acid O b. Succinic Acid O c. Oxalic Acid O d. Potassium Hydrogen Phthalate O e. Sulfamic Acid O f. Citric Acid
