Question

2Fe(N03)3 + 2KI → 2Fe(N03)2 + I2 + 2KNO3

 Zn + 2Fe(N03)3 → Zn(N03)2 + 2Fe(N03)2

viết ra pt ion đc ko ????????????????????????

 

Answer 1

\(2Fe^{3+} + 6NO_3^- + 2K^+ + 2I^- \to 2Fe^{2+} + 5NO_3^- + I_2 + 2K^+ + 2NO_3^-\\ Zn + 2Fe^{3+} + 6NO_3^- \to Zn^{2+} + 2NO_3^- + 2Fe^{2+} + 4NO_3^-\)

Answer 2

\(2Fe^{3+}+2I^-\rightarrow2Fe^{2+}+I_2\)

\(Zn+2Fe^{3+}\rightarrow Zn^{2+}+2Fe^{2+}\)
