Introduction

In chemistry, a displacement reaction is a type of chemical reaction where one element displaces another element from a compound. This type of reaction is commonly observed in metal-metal reactions, where a more reactive metal displaces a less reactive metal from a compound. In this article, we will discuss the concept of displacement reaction and identify which metal will displace nickel in a compound.

What is Displacement Reaction?

A displacement reaction is a type of chemical reaction where one element displaces another element from a compound. This type of reaction is also known as a substitution reaction. In a displacement reaction, the more reactive element displaces the less reactive element from the compound. The general equation for a displacement reaction is:

A + BC → AC + B

Where A and B are elements, and C is a compound.

Factors Affecting Displacement Reaction

There are several factors that affect the displacement reaction, including:

Reactivity of the elements: The reactivity of the elements involved in the reaction plays a crucial role in determining the outcome of the reaction. A more reactive element will displace a less reactive element from a compound.
Electronegativity of the elements: The electronegativity of the elements involved in the reaction also affects the outcome of the reaction. Elements with high electronegativity values tend to displace elements with low electronegativity values.
Oxidation state of the elements: The oxidation state of the elements involved in the reaction also affects the outcome of the reaction. Elements with a higher oxidation state tend to displace elements with a lower oxidation state.

Displacement Reaction of Nickel

Nickel is a transition metal that is commonly used in various applications, including catalysis, corrosion resistance, and magnetic materials. In a displacement reaction, nickel can be displaced by a more reactive metal. The question is, which metal will displace nickel in a compound?

Options

There are four options available: Platinum, Tin, Zinc, and Arsenic. Let's analyze each option:

A) Platinum

Platinum is a noble metal that is highly unreactive. It is not likely to displace nickel in a compound, as it is less reactive than nickel.

B) Tin

Tin is a post-transition metal that is less reactive than nickel. It is not likely to displace nickel in a compound, as it is less reactive than nickel.

C) Zinc

Zinc is a post-transition metal that is more reactive than nickel. It has a higher reactivity than nickel and can displace nickel in a compound.

D) Arsenic

Arsenic is a metalloid that is less reactive than nickel. It is not likely to displace nickel in a compound, as it is less reactive than nickel.

Conclusion

Based on the analysis of the options, the correct answer is C) Zinc. Zinc is a more reactive metal than nickel and can displace nickel in a compound. The displacement reaction of nickel by zinc can be represented by the following equation:

Zn + NiCl2 → ZnCl2 + Ni

This reaction is a classic example of a displacement reaction, where zinc displaces nickel from a compound.

Importance of Displacement Reaction

Displacement reaction is an important concept in chemistry that has various applications in different fields, including:

Metallurgy: Displacement reaction is used in the extraction of metals from their ores.
Catalysis: Displacement reaction is used in the development of catalysts for various chemical reactions.
Corrosion resistance: Displacement reaction is used to develop corrosion-resistant materials.

Conclusion
