Observations: Organic Compound | Water | 1.0 M NaOH | 1.0 M HCl Benzoic Acid | Insoluble | Soluble | Insoluble Add 6.0 M HCl: Insoluble Ethyl 4-aminobenzoate | Insoluble | Insoluble | Soluble Add 6.0 M NaOH: Insoluble 6.) Explain the chemistry behind the changes in solubility observed for each compound from the data given in the table above, separately. (Hint: Mentioning protonation/deprotonation would be wise.) (2 pts) 7.) Write the balanced chemical reaction for each soluble reaction above (separately) and label each component in each reaction as either acid, base, conjugate acid, or conjugate base.

What would be the expected solubility of sodium benzoate, the structure of which is shown below? sodium benzoate It would be soluble in ether and insoluble in water It would be soluble in water and insoluble in ether It would be soluble in both ether and water It would be insoluble in both ether and water

Benzoic acid (C6H5COOH) is insoluble in water at room temperature, but soluble in ethyl acetate. By comparison, sodium benzoate (C6H5COONa) is soluble in water at room temperature. Briefly describe how, by manipulating pH and performing an extraction, you might form and subsequently extract a benzoic acid precipitate from an aqueous solution of sodium benzoate.
