Answer:

acidic substances is H2CO3

Answer 2

The acidic substance is c)$H_{2}CO_{3}$ .

Acids

• Acidic substances are generally distinguished by their harsh taste. A corrosive is essentially a particle which can give a $H^{+}$particle and can remain vigorously great after a deficiency of $H^{+}$ Acids is known to become blue litmus red.
• Bases, then again, are described by a harsh taste and a tricky surface. A base that can be degraded up in the solvent is alluded to as salt. When these substances artificially react with acids, they yield salts. Bases are known to become red litmus blue.
• Carbonic acid is a speculative corrosive, made out of carbon dioxide and water having the synthetic recipe $H_{2}CO_{3}$ . It is a dibasic corrosive since it contains two replaceable hydrogen iotas. It plays a part as a metabolite.
• $H_{2}CO_{3}$ is viewed as corrosive. Since on dissolving in a fluid arrangement, it separates into two particles ($H^{+}$ and $HCO^{-} _{3}$) and whatever outfits proton particle in an answer is considered corrosive in nature.
