Transcribed Image Text: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.

- A strong acid-strong base titration was performed as follows: 10.00 mL of 0.10M HCl were collected in an Erlenmeyer flask, and then diluted to 100 mL with distilled water. After that, two drops of indicator were added. Then, the buret was filled with 0.100 M NaOH. The titration was started by slowly adding NaOH to HCl. (Note: The volume of two drops indicator is ignored as it is so tiny compared with 100 mL.) What is the pH of the solution in the Erlenmeyer flask after adding 10.20 ml of 0.100M NaOH?
