Question

Which factor below could cause your experimental yield to be less than your calculated theoretical yield?

1. you have an incomplete reaction

2. you miscalculated the theoretical yield and it was smaller than it should be

3. your product may contain small amounts of solvent

4. your seperation technique did not completely seperate the product from the other reaction products

what might happen if you make the solution containing the benzoic acid precipitate basic rather than acidic?

1. the solution would start foaming due to production of CO2 gas

2. the precipitate would dissolve

3. benzaldehyde would precipitate out of solution

4. there would be no change

assume you are given benzoic acid and are asked to dissolve it in an aqueous solution. how could this be done?

1. cool the solution to 10 deg C

2. add NaOH to the solution to increase pH

3. add NaCl to the water

4. add HCl to the solution to decrease the pH
