Question

What is meant by denatured alcohol?
What is the need to denature alcohol?
. Write chemical equations of the reactions of ethanoic acid with
(a) Sodium (b) Sodium carbonate
(c) Ethanol (d) The presence of conc H2So4

Answer 1

denatured alcohol ------
when alcohol mixed with copper sulphate and pyridine, a foul smelling liquid is formed which is unfit for drinking. It is called denatured alcohol

Answer 2

Here is your answer mate!!

=>Denatured Alcohol:

Potable alcohol (alcoholic beverages) is costly. Government levies high excessive duty on the sale of the drinking. But alcohol meant to be used in industries is cheap.

=>Need To Denature Alcohol:

To prevent the misuse of industrial alcohol for drinking purposes, alcohol is denatured. That is it made unfit for drinking. This can be done either by mixing methanol to ethanol or adding some dye to it.

=>Chemical Equation's:

(1)Sodium:

CH3COOH + NA ----------------------) CH3COONA + H2.

CH3COONA ----------- Sodium Ethanoate.

(2)Sodium Carbonate:

CH3COOH + NaOH--------------------) CH3COONA + H2O.

CH3COONA ----------- Sodium Ethanoate.

(3)Ethanol:

CH3COOH + C2H5OH-----------------------) CH3COOC2H5 + H2O

CH3COOC2H5 -------- Ethyl ethanoate(ester)

(4)The presence of concentrated H2SO4:

CH3COOH + C2H5OH ---------------------) Conc.H2SO4→ CH3COOH + H2O
