The acid ionization hydrolysis constant of ${\text{Zn}}^{\text{2+}}{\text{\hspace{0.17em}is\hspace{0.17em}1.0\hspace{0.17em}×\hspace{0.17em}10}}^{\text{-9}}$ which of the following statement are

incorrect?

The $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ ion concentration in 0.001 M ${\text{ZnCl}}_2$ solution is $1.0\times {10}^{-4}$

The pH of 0.001 M ${\text{ZnCl}}_2$solution is 6
