Which of the Following Does not Form an Acidic Salt (A) Phosphoric acid (B) Carbonic acid (C) Hydrochloric acid (D) Sulphuric acid

Answer: The correct option is B or Carbonic acid.

Carbonic acid, with the chemical formula H₂CO₃, is a carbon-containing compound. This compound is found in small amounts of carbon dioxide solutions in water. As it is a weak acid, it doesn’t form acidic salts. H₂CO₃ is not a strong acid that reacts to form an (H+ cation) proton as well as an (HCO₃– anion) bicarbonate ion. In aqueous solutions, this compound only partially dissociates.
