Solubility of Organic Compounds Lab Report

Place about 30 mg (0 030 g) of benzoic acid into each of two dry test tubes Label the test tubes and then add 1 mL of water to the 1st tube and 1 mL of 1 0 M NaOH to the 2nd tube Shake each tube for 10-20 seconds Note whether the compound is soluble (dissolves completely) or is insoluble (none of it dissolves) Record these results in table Now take the tube containing benzoic acid and 1 0

Benzoic acid — Wikipedia Republished // WIKI 2

Benzoic acid was discovered in the sixteenth century The dry distillation of gum benzoin was first described by Nostradamus (1556) and then by Alexius Pedemontanus (1560) and Blaise de Vigenre (1596) Pioneer work in 1830 through a variety of experiences based on amygdalin obtained from bitter almonds (the fruit of Prunus dulcis) oil by Pierre Robiquet and Antoine Boutron-Charlard two

Recrystallization Introduction

Benzoic acid is not very soluble in cold water but it is soluble in hot water The purpose of this experiment is to learn the technique of recrystallization by purifying benzoic acid Measuring Melting Points - The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid A solid compound changes to a liquid when the molecules acquire enough energy
