Write the major species in the water solution of each substance given. Write the hydronium ion as H+ and do not write coeffients with ions.

a. Ca(ClO4)2
b. HI
c. HC2H3O2

a. The major species are Ca²⁺ and ClO₄⁻.

b. The major species are H⁺ and I⁻.

c. The major species are H⁺ and C₂H₃O₂⁻.

Explanation:

Hello there!

In this case, according to the required, we need to firstly tell that both Ca(ClO4)2 and HI undergo a complete ionization as the former is an ionic salt and the latter is a strong acid. Moreover, the HC2H3O2 is a weak acid, so its dissociation is not complete. In such a way, we can proceed as follows:

a.

Thus, the major species are Ca²⁺ and ClO₄⁻.

b.

Thus, the major species are H⁺ and I⁻.

c.

Thus, the major species are H⁺ and C₂H₃O₂⁻.

Regards!
