The decreasing power will be greater the lower the reduction potential.
Ag<Ni<Zn<Na
Ag has the least reducing power, followed by Zn, Ni, and lastly Na, which all have high reducing powers.
What is reducing power and reducing agent?
A chemical species' ability to cause another chemical substance to undergo reduction is known as its reducing power. Reducing agents are the chemical compounds that have this property. While the other molecule goes through reduction, the reducing agent goes through oxidation.
Why does reducing power increase down a group?
From top to bottom, the group's ionization potential and electron affinity decrease. As a result, there is an increased tendency to lose electrons, which causes the reducing characteristic to rise across the group from top to bottom.
