Chapter 22: Problem 15

What is the action of dilute and conc. acids on oxides of uranium, thorium and plutonium? Give chemical reactions in support of your answer.

Short Answer

Expert verified

When reacted with dilute or concentrated acids, oxides of uranium, thorium, and plutonium form their respective chlorides and water. The quantities of the chlorides and water vary based on the acidity

Step by step solution

Oxide of Uranium Reaction with Dilute Acid

Let's consider uranium oxide (UO3). When UO3 reacts with a dilute acid (such as hydrochloric acid, HCl), it forms uranium chloride and water. The chemical reaction can be written as: \(UO3 + 6HCl \rightarrow UCl6 + 3H2O\)

Oxide of Uranium Reaction with Concentrated Acid

When uranium oxide (UO3) reacts with concentrated acid, uranium chloride and water are again formed, but the concentrated acid proportion is different. For concentrated acid, reaction can be written as: \(UO3 + 6HCl \rightarrow UCl6 + 6H2O\)

Oxide of Thorium Reaction with Dilute Acid

Thorium oxide (ThO2) will react with a dilute acid (such as hydrochloric acid, HCl), forming thorium chloride and water. We can write this chemical reaction as: \(ThO2 + 4HCl \rightarrow ThCl4 + 2H2O\)

Oxide of Thorium Reaction with Concentrated Acid

When thorium oxide reacts with concentrated hydrochloric acid, it will again form thorium chloride and water, but in different proportions. For a concentrated acid, reaction is given by: \(ThO2 + 8HCl \rightarrow ThCl4 + 4H2O\)

Oxide of Plutonium Reaction with Dilute Acid

Plutonium oxide (PuO2) reacts with a dilute acid (like hydrochloric acid, HCl) to form plutonium chloride and water. The reaction is: \(PuO2 + 4HCl \rightarrow PuCl4 + 2H2O\)

Oxide of Plutonium Reaction with Concentrated Acid

When plutonium oxide reacts with concentrated acid, plutonium chloride and water are again formed, but in larger quantities due to the acidity. For concentrated acid, reaction is given by: \(PuO2 + 8HCl \rightarrow PuCl4 + 4H2O\)
