Chemistry 1223 Molar Weight of a Solid Acid Laboratory Exercise An unknown acid is chosen from the list in the 1223 Lab Procedure. Determine the Identify the unknown 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 mL aliquote was titrated with NaOH. 24.73 mL of titrant was required. Determine the concentration of sodium hydroxide. Answer: Part 2: Titration of the diprotic 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 diprotic unknown. units g/mol Answer: MyASUS
