NaHCO3​

Answer 1

Among the given substances, CH₃COOH is corrosive.

• Corrosive substances are defined as compounds that can potentially damage other materials if they come in contact. They are a great risk to the people as well as the environment.

• Acetic acid or ethanoic acid (IUPAC name) is an organic compound that majorly used in vinegar. It is corrosive in nature. The vapours of acetic acid act as an irritant to the eyes and nose.

Answer 2

Acetic acid i.e "CH3COOH" is corrosive in nature.

Explanation:

• CH3COOH is known as "acetic acid" and it gives a neutralization reaction.
• When it reacts with sodium hydroxide it forms water and salt of acetic acid.
• The chemical reaction is given below.
• NaOH + CH3COOH -----> CH3COOHNa + H2O
• It is very corrosive in nature as it gives corrosion reactions.
• acetic acid also causes mild corrosion of steel surface and is also harmful to the environment.
