Question

4. What is the purpose of adjusting the polarity?

5. Would benzoic acid dissolve better in water, or in ethanol? Explain why using the concepts discussed in this laboratory.

Answer 1

4. The purpose of adjusting polarity is because molecules with high polarity are hydrophilic and mix well with other compounds like water.

5. Benzoic acid will dissolve better in ethanol than water because it is of a polar carboxylic group and the bulk amount of benzoic acid is non polar.
