(a)
Interpretation:
Based on the effective nuclear charge, the strongest and weakest reducing agent has to be identified from the given ions.
Concept Introduction:
Effective nuclear charge:
The overall nuclear charge felt by an electron is known as effective nuclear charge. Because, the attraction between nucleus and the outer shell electron is reduced by the inner shell electrons. This effect is described by saying outer electrons are shielded from the nucleus by the inner electrons.
The value of

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.
