    Ester water Particularly‚ 1-hexanol was reacted with an excess of acetic acid‚ using an acid catalyst to yield its ester: hexyl acetate. The reaction was performed under reflux which sped up the reaction by continuous vapor-condensation cycles of the solution mixture as the solution boiled. The vapors were blocked from escaping the solution by a stream of cold water running up the

    dissolves like”‚ fluorene dissolves with the non-polar heptane and the polar fluorenone dissolves in the polar ethyl acetate solvent. This phenomenon was illustrated in class before the experiment‚ when it was pointed out why water will not dissolve fluorene‚ fluorenone‚ or transstilbene as readily as a nonpolar solvent such as heptane or toluene‚ or a polar eluent such as ethyl acetate. Those solvents have a much more similar structure to the solutes‚ whereas water’s structure is much different‚ making

    of sodium ions and bicarbonate ions. These two solutions mixed together produce two separate reactions. The first is an acid-base reaction producing carbonic acid (H2CO3) and sodium acetate(CH₃COONa). The second is a decomposition reaction of carbonic acid to produce water (H₂O)‚ carbon dioxide gas (CO₂). Sodium acetate is the sodium salt of acetic acid. The balanced equation for this reaction
