Question

33.

Consider an opened bottle of wine.

When wine (ethanol) is left open for too long it develops the "vinegary" taste of ethanoic acid. Explain the reaction that is occurring.

Your friend's parent states you can slow the rate of this reaction down by storing the opened (and resealed) wine bottle laying on its side. Agree or disagree and justify your response using what you know of chemistry.

Answer 1

The answer is explainein the figure attached here,

The reaction of Ethanol with Oxidis in a gents ie oxygen from the air ai ethgroic acid (acetic acid). The oxidation of ethanol by microorganism that grows in wine left open to the air leads to acetic acid / ethandic acid. 3) this reaction is catalyzed by the microorganisms present in the wine, as wine is of biological origine.
