Question: 6. (3 pts) Ethyl 4-aminobenzoate was not soluble in pure water or sodium hydroxide. However, the compound was quite soluble in 1.0 M HCI.
Does Ethyl 4-aminobenzoate dissolve in HCl?
The majority of the data claims that Ethyl 4-aminobenzoate is soluble in 1.0 HCl, but insoluble when 6.0 NaOH is added.
Is benzocaine an acid or base?
Benzocaine is a benzoate ester having 4-aminobenzoic acid as the acid component and ethanol as the alcohol component.
Is benzoic acid soluble in NaOH?
For example, benzoic acid is not soluble in water, yet it is soluble in sodium hydroxide solution and in sodium hydrogen carbonate solution because these bases react with benzoic acid to form the water-soluble benzoate ion.
Is ethyl 4 Aminobenzoate polar or nonpolar?
Why is 4-ethyl aminobenzoate considered nonpolar? : r/chemistry.

Is benzocaine soluble in ethyl acetate?
The solubility of both polymorphs has been determined in eight pure organic solvents over the temperature range 278 K–323 K by a gravimetric method. The mole fraction solubility of benzocaine decreases in the order: 1,4-dioxane, acetone, ethyl acetate, chloroform, acetonitrile, methanol, n-butanol and toluene.
Is ethyl 4 Aminobenzoate polar?
What is soluble in NaOH?

Are phenols soluble in NaOH?
Answer: Phenols show acidic nature and hence are soluble in alkalies like NaOH, Na2CO3 etc. The acidic nature is due to formation of resonance stabilized phenoxide ion formed by losing a proton from -OH group.
Is NaOH polar or nonpolar?
In alkali metal hydroxides, such as NaOH, the Na-O bond is most polar. The electronegativity difference between sodium and oxygen is larger than that between oxygen and hydrogen.
