Using your calculated concentration of NaOH from lab how many grams of KHP would you need to start with in order to have an end point at 35.00 mL?
Do I use 71.08 or 204.22 for KHP Molecular Mass? Concentration of NaOH from the Experiment was .356.

Both compounds prepared in this experiment must be distinguishable from one another. Determine 3 physical tests that can be done to distinguish the two isomers. Then, write simple procedures to carry out the actual tests using available lab equipment.
compounds: Maleic acid and Fumaric acid

In each of the titrations performed in this experiment, the end point was apparent due to a color change in the material being oxidized or reduced. Suppose that none of the materials involved in the redox reaction are colored. Suggest a way one could determine the endpoint in such a case. (Hint= Think about acid-base titrations)
