If a Reaction Occurs, What Will Be the Products of the Unbalanced Reaction Below?

Understanding the Activity Series of Elements

The activity series of elements is a list of metals in order of their reactivity, from most reactive to least reactive. This series helps us predict which metals will displace other metals from their solutions. In the given reaction, copper (Cu) is reacting with nickel(II) nitrate (Ni(NO3)2). To determine the products of the unbalanced reaction, we need to understand the activity series of elements.

The Activity Series of Elements: A Key to Predicting Reaction Products

The activity series of elements is as follows:

Potassium (K)
Sodium (Na)
Calcium (Ca)
Magnesium (Mg)
Aluminum (Al)
Zinc (Zn)
Iron (Fe)
Tin (Sn)
Lead (Pb)
Hydrogen (H2)
Copper (Cu)
Silver (Ag)
Gold (Au)
Platinum (Pt)

In the given reaction, copper (Cu) is reacting with nickel(II) nitrate (Ni(NO3)2). According to the activity series, copper is less reactive than nickel. This means that copper will not displace nickel from its solution.

Predicting the Products of the Unbalanced Reaction

Given the activity series of elements, we can predict the products of the unbalanced reaction. Since copper is less reactive than nickel, it will not displace nickel from its solution. Therefore, the products of the unbalanced reaction will be:

${ Cu(s) + Ni\left(NO_3\right)_2(aq) \rightarrow Cu(NO_3)_2(aq) + Ni(s) }$

However, this is not the only possible product. Another possible product is:

${ Cu(s) + Ni\left(NO_3\right)_2(aq) \rightarrow CuNi(s) + NO_2(g) }$

This product is more likely to occur because copper and nickel can form an alloy, which is a mixture of two or more elements. In this case, the alloy formed is copper-nickel (CuNi).

Understanding the Role of Nitric Acid

In the given reaction, nickel(II) nitrate (Ni(NO3)2) is the reactant. Nitric acid (HNO3) is a strong acid that can dissociate in water to form hydrogen ions (H+) and nitrate ions (NO3-). The nitrate ions can then react with copper to form copper(II) nitrate (Cu(NO3)2).

The Role of Copper in the Reaction

The Role of Nitrogen Dioxide

Nitrogen dioxide (NO2) is a product of the reaction between copper and nickel(II) nitrate (Ni(NO3)2). Nitrogen dioxide is a toxic gas that can react with water to form nitric acid (HNO3).
