Ni (II) compounds are thermodynamically more stable with Pt(II) compounds.

Text Solution

AI Generated Solution

To determine whether Ni(II) compounds are thermodynamically more stable than Pt(II) compounds, we need to analyze the factors that influence the stability of these compounds. ### Step 1: Understanding Ionization Energy - **Explanation**: Ionization energy is the energy required to remove an electron from an atom or ion. A lower ionization energy generally indicates that an element can lose electrons more easily, which can affect the stability of its compounds. - **Hint**: Consider how the position of nickel and platinum in the periodic table affects their ionization energies. ### Step 2: Comparing Ionization Energies of Ni(II) and Pt(II) - **Explanation**: Nickel (Ni) has a lower ionization energy compared to platinum (Pt). This means that Ni(II) can be formed more easily than Pt(II). The lower ionization energy of nickel contributes to the stability of its +2 oxidation state. ...
