Write the reaction equations: ethanol-ethanal-acetic acid-potassium acetate-acetic acid

1. To solve, we write down the chain of transformations:
С2Н5ОН – СН3 – СОН – СН3СООН – СН3СООК – СН3СООН.
2. Let’s compose the equations:
С2Н5ОН + CuO = CH3 – COH + Cu + H2O – alcohol oxidation with copper oxide, ethanal and copper were obtained;
CH3 – СОН + Ag2O = CH3 – COOH + 2Ag – acetic acid and silver are released during the reaction of a silver mirror;
2СН3СООН + 2K = 2CH3COOK + H2 – substitutions, potassium acetate, hydrogen was formed;
CH3COOK + HCl = CH3COOH + KCl – exchange, acetic acid was obtained.
3. The solution process shows the relationship between the classes of oxygenated organic substances: alcohols, aldehydes, carboxylic acids. The final product, acetic acid, is used in the food industry for canning.
