Reaction of ethanoic acid with a metal

Answer 1

ethanoic acid + metal → metal ethanoate + hydrogen

Question 2

Neutralisation reaction with ethanoic acid and metal hydroxide

Answer 2

ethanoic acid + metal hydroxide → metal ethanoate + water

Question 3

Reaction of ethanoic acid with sodium carbonate

Answer 3

ethanoic acid + sodium carbonate → sodium ethanoate + carbon dioxide + water

Question 4

Functional group of carboxylic acids?

Answer 4

• COOH

Question 5

Answer 6

Concentrated sulfuric acid

Question 7

How do you name an ester?
