Question

• B. They react with alkalies
• C. They burn the skin
• D. They contain $H$-atom replaceable with metal

Answer 1

Answer: (A), (B), (D)

They react with alkalies
They turn litmus red
They contain $H$-atom replaceable with metal

Bronsted acids: Any chemical species that acts as a donor of protons are Bronsted acids.

Acids turn blue litmus paper red.

They can also react with alkalies to form water.

Since, they are proton donor, they contain H atoms which can be replaced with metals during acid-base reaction.

Ethanoic acid is Bronsted acid but doesn't burn the skin.
