Question

2. Use the CRC Handbook or Merck Index to determine the formulas and molar masses of the following dicarboxylic acids. These books can be found in the college library or the chemistry lab. Note, dicarboxylic acids usually have several names; do not let this confuse you. For instance succinic acid can also be called amber acid, asuccin, butanedioic acid, 1,2- ethanedicarboxylic acid, ethylenesuccinic acid, wormwood, or wormwood acid, Hint you will need this information for your report. So, be sure to keep a copy se word bare to look up again!

Palmitic acid is a carboxylic acid with the formula CH,(CH)..CO.H. What is the balanced equation for the reaction of palmitic acid with aqueous potassium hydroxide? Be sure you include states in your equation. 4. Fumaric acid is a dicarboxylic acid with the formula HO.C(CH),CO.H. What is the balanced equation for the reaction of fumatic acid with aqueous sodium hydroxide? Be sure you include states in your equation. 5. In a titration similar to the one you will perform today, it is found that 24.66 mL of 0.1012 M NaOH is required to titrate 0.2524 g of an unknown dicarboxylic acid. What is the molar mass of this unknown dicarboxylic acid?
