Question

Consider a 0.10 M H₂CO₃ solution and a 0.10 M H₂SO₄ solution. Without doing any detailed calculations, choose one of the following statements that best describes the [H⁺] of each solution and explain your answer.

a. The [H⁺] is less than 0.10 M.

b. The [H⁺] is 0.10 M.

c. The [H⁺] is between 0.10 M and 0.20 M.

d. The [H⁺] is 0.20 M

Short answer

Answer is c that means [H+] ion concentration is in between 0.10 M and 0.20 M.

Step-by-step solution

Dissociation of H2SO4

As H₂SO₄ is a strong acid so, it will completely dissociate and will give [H⁺] =0.1M.

Dissociation of H2CO3

H₂CO₃ is a weak acid so, it will not completely dissociate and will give [H⁺] less than 0.1M (own concentration).So total [H⁺] will be in between 0.10 M to 0.20 M.
