Answer:

Explanation:

Ionjc equation

ZnCl2 --> Zn2+ + 2Cl-

CdCl2 --> Cd2+ + 2Cl-

Both Cd2+ and Zn2+ have the same number of charge so lewis acid does not apply. Zn2+ has a smaller radius than Cd2+ hence it will produce a more acidic solution.

Ionic equation

Ca(NO3)2 --> Ca2+ + 2NO3^-

NiBr2 --> Ni2+ + 2Br-

Both Ni2+ and Ca2+ have the same number of charge so lewis acid does not apply. Ni2+ has a smaller radius than Ca2+ hence it will produce a more acidic solution.

Ionic equation

CuCl --> Cu+ + Cl-

Cu(NO3)2 --> Cu2+ + 2NO3^-

The hardness of a lewis acid increases with increasing positive charge, as the electron density is more concentrated. Therefore, Cu2+ is the stonger acid in solution than Cu+, being less polarizable that is the strength to pull electrons in Cu2+ is stronger.
