Prelab 2- Na Benzoate acidification (10 m)
Diagram the reaction you are carrying out and name the reactants and products? 2m
Are the reactants both soluble in water? 1m
In the above equation what is the number of molecules of each reactant and what is the number of each of the molecular products? 1m
What do you think is the identity of the solid precipitate seen in this reaction? 1m
Which of the two products of the reaction will remain in solution ( ie will not precipitate)? 1m
How will you obtain the dry precipitate? 2m
How does this experiment mimic the action of the stomach on a food preservative? 2m
Homework Answers
1.Considering the acid used to be HCl
C6H5COONa + HCl==> NaCl + C6H5COOH
2. When sodium benzoate dissolved in water it dissociates as sodium ions and benzoic acid.
3. The no. of molecules of reactants and products are 1 each.
4.The solid precipitate formed in the reaction is the Benzioc acid.

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
