FAQs on Trends in Standard Electrode Potential of d-Block Elements

Question 1

1. What is the trend in the standard electrode potential of d-block elements?

Accepted Answer

Ans. The trend in the standard electrode potential of d-block elements is generally based on their position in the periodic table. As we move across a period from left to right, the standard electrode potential generally decreases. On the other hand, as we move down a group, the standard electrode potential generally increases.

Question 2

2. How does the standard electrode potential of d-block elements relate to their reactivity?

Accepted Answer

Ans. The standard electrode potential of d-block elements is related to their reactivity. Generally, elements with a higher standard electrode potential are more reactive, as they are more likely to lose electrons and undergo oxidation. In contrast, elements with a lower standard electrode potential are less reactive and tend to gain electrons, undergoing reduction reactions.

Question 3

3. What factors affect the standard electrode potential of d-block elements?

Accepted Answer

Ans. Several factors can affect the standard electrode potential of d-block elements. These factors include atomic size, effective nuclear charge, electron-electron repulsion, and the stability of oxidation states. For example, elements with a smaller atomic size and higher effective nuclear charge tend to have a higher standard electrode potential.

Question 4

4. How is the standard electrode potential of d-block elements measured?

Accepted Answer

Ans. The standard electrode potential of d-block elements is measured using a standard hydrogen electrode as a reference. In this setup, the d-block element is connected to the standard hydrogen electrode through a salt bridge, and a voltmeter is used to measure the potential difference between the two electrodes. The standard electrode potential is then calculated by subtracting the potential of the standard hydrogen electrode from the measured potential.

Question 5

5. What are the practical applications of understanding the trend in the standard electrode potential of d-block elements?

Accepted Answer

Ans. Understanding the trend in the standard electrode potential of d-block elements has several practical applications. It can be used to predict and explain the reactivity of d-block elements in various chemical reactions. Additionally, it is crucial in electrochemical processes, such as corrosion prevention and electroplating. The knowledge of standard electrode potential also plays a role in designing and optimizing electrochemical cells and batteries.
