only the questions pls disregard the experiment results thank you

Experimental results: Acetic acid Benzoic acid Phenol Reaction with NaOH Reaction with NaHCO3 Ferric chloride test Tollen's test Esterification Hydrolysis of ethyl acetate Questions: 1) Explain the solubility of acetic acid in water. 2) Discuss the molecular basis for the reaction of tollen's reagent with acetic acid that leads to the formation of silver precipitate. 3) What is the purpose of boiling chips? 4) What are the products of esterification reaction? 5) What are the products of the hydrolysis of ethyl acetate?

TESTS FOR CARBOXYLIC ACIDS Materials: Test tube – 12 Test tube rack - 1 Water bath – 1 Test tube holder – 1 Tripod -1 Graduated cylinder (100mL) – 1 Crucible tong -1 Wire gauze - 1 Condenser - 1 Round bottom flask-1 Iron clamp - 2 Iron stand - 2 Heating mantle - 1 Chemicals: Diluted NaOH solution Acetic acid 5% N2OH soln Benzoic acid 5% NAHCO, Phenol Ferric chloride solution Tollen's reagent Procedure: A) Reaction with sodium hydroxide Place 3 ml of acetic acid into a test tube and add 2 ml of 5% NaOH. Shake and note the solubility. Repeat using 1g of benzoic acid. B) Reaction with sodium bicarbonate Place 1 ml of acetic acid into a test tube and add 1 ml of 5% NaHCO, solution. Shake and note the solubility. Repeat using 1 mL of phenol. C) Ferric chloride test Place 1 ml of acetic acid into a test tube and add 1 ml of dilute NaOH. Add 5 drops of ferric chloride solution. Boil and note the color changes. D) Tollen's test Place 1 ml of acetic acid into a test tube and add 1 ml of tollen's reagent. Warm in water bath and take note of the silver mirror formed. E) Esterification Place 1 ml of acetic acid into a test tube and add 1 ml of ethanol. Add 2 drops of conc. sulfuric acid. Warm in water bath and take note of the odor of the product formed. F) Hydrolysis of esters Place 30 ml of ethyl acetate into a small round bottom flask. Add 10 ml of 5% NaOH soln and boiling chips. Attach condenser and reflux for 30 minutes. Cool the flux and acidify with dilute acid.
