The major product formed by the reaction between ethanoic acid and aqueous sodium hydroxide is

The major product formed by the reaction between ethanoic acid and aqueous sodium hydroxide is sodium ethanoate, which is a salt. When ethanoic acid reacts with aqueous sodium hydroxide, the acid-base neutralization reaction occurs, and the products are sodium ethanoate (the salt) and water. Sodium hydroxide is a strong base, and ethanoic acid is a weak acid, so the reaction favors the formation of the salt. The reaction can be represented by the following chemical equation: CH\(_3\)COOH + NaOH → CH\(_3\)COONa + H\(_2\)O Therefore, the major product of the reaction is sodium ethanoate, and the other product is water.
