Question

write the properties of ethanoic acid? answer me fast plz​

Answer 1

$\Large{\underline{\boxed{\mathbb \orange{ETHANOIC \: ACID:}}}}$

• Ethanoic acid is the second memeber of homologus series of carboxylic acid. The formula of ethanoic acid is $\sf\ CH_3 COOH.$
• The common name of ethanoic acid is Acetic acid. A dilute solution of ethanoic acid in water is called Vinegar. Vinegar contains about 5 to 8% ethanoic acid or In other words Vinegar contains about 5 to 8% Acetic acid.Vinegar is used widely as a "preservative in pickles"

$\Large{\underline{\boxed{\mathbb \orange{PROPERTIES \: OF \: ACID:}}}}$

⠀⠀⠀Chemical Properties :

• Action on Litmus : Ethanoic acid is acidic in nature. Being acidic in nature, acid turns blue litmus to red.
• Reaction with carbonates and hydrogencarbonates : Ethanoic acid reacts with carbonates and hydrogencarbonates to form carbon dioxide gas along with the formation of salt and water.
• Reaction with Sodium hydroxide : Ethanoic acid reacts with bases or alkalis to form salt and water.
• Reaction with Alcohols : Ethanoic acid react with alcohols in the presence of a little of concentrated sulphuric acid to form "Esters".

⠀⠀⠀Physical Properties :

• Ethanoic acid is a colorless liquid having a sour taste and smell of Vinegar.
• The boiling point of Ethanoic acid is 118°C (or 391k).
• Ethanoic acid is miscible with water in all properties.
• When pure Ethanoic acid is cooled, it freezes to form a colorless, ice like solid (which looks a glacier).Due to this ethanoic acid is called Glacial acetic acid.

Answer 2

Answer:

HEY Buddy here's ur answer

Physical properties :

(i) Ethanoic acid is vinegar smelling liquid. The lower carboxylic acids are liquids whereas higher ones are solids.

(ii) Ethanoic acid is sour in taste. Other lower carboxylic acids are also sour in taste.

(iii) Ethanoic acid has boiling point 391 K. Carboxylic acids have higher boiling points than corresponding alcohols, aldehydes and ketones.

(iv) Acetic acid is soluble in water, i.e., it is miscible with water in all proportions. The lower carboxylic acids are soluble in water but solubility in water decreases with increase in molecular weight.

(v) Acetic acid freezes at 290 K. Thus, in cold weather crystallization of acetic acid may take place that is why pure acetic acid is called glacial acetic acid.

Chemical Properties :

(i) Ethanoic acid is weak acid but it turns blue litmus red.

(ii) Reaction with Metale. Ethanoic acid reacts with metals like Na, K, Zn etc. to form metal ethanoates and hydrogen gas.

(iii) Reaction with Carbonates. Ethanoic acid reacts with bicarbonates and carbonates and produces brisk effervescence due to formation of carbon dioxide, CO2.

(iv) Reaction with Base. Ethanoic acid reacts with sodium hydroxide to form sodium ethanoate and water.

(v) Decarboxylation (Removal of CO2) When sodium salt of ethanoic acid, i.e., sodium ethanoate is heated with soda lime (3 parts of NaOH and 1 part of CaO), methane gas is formed.
