Question

What ${H_2}C{O_3}$ is :
A. Strong acid
B. Weak acid
C. Strong base
D. Weak acid

Answer 1

Hint: In this question we will be seeing the nature of the acids. We will be learning how strong or weak acids are and the reason behind it. We will be learning about something called respiratory acid.Acid, any substance that in water solution tastes acrid, changes the color of specific indicators (e.g., reddens blue litmus paper), responds with certain metals (e.g., iron) to release hydrogen, responds with bases to frame salts, and advances certain chemical reactions (acid catalysis).

Complete step by step answer:
Carbonic acid is a feeble acid which doesn't separate totally to give hydrogen particles in solution. It is framed in small quantities when its anhydride carbon dioxide breaks up in water. In physiology it is referred to as respiratory acid as it is the main corrosive discharged as a gas by lungs.

So the answer is option A.

Additional Information:
How to categorize weak and strong acids?
Strong acids and bases are 100% ionized in aqueous solution. weak acids and bases are not 100% ionized in aqueous solution. Salts of weak acids or bases can influence the corrosiveness or basicity of their aqueous solution.

Note: To solve this question, one must know the entire concept of acids and all about the strong and weak acids so that one can categorize which acid is a weak one or a strong one. One needs to know what makes an acid weak or strong, basing that they can answer the above question.
