What happens when Tungsten Chloride Reacts with Nitric Acid

Understanding chemical reactions can be crucial in fields such as chemistry and engineering. One reaction to explore is when tungsten chloride reacts with nitric acid, which produces a variety of products. Let’s break down this reaction and understand the implications it has for scientists and engineers.

Reaction Process

Tungsten chloride (WCl6) is a compound composed of one tungsten atom and six chlorine atoms that are connected to the central tungsten atom via covalent bonds. When this compound comes into contact with nitric acid (HNO3), a reaction occurs where the nitric acid will provide oxygen ions to the tungsten chloride molecules. This results in two different compounds being produced: tungstic oxide (WO3) and hydrochloric acid (HCl). The equation for this reaction is WCl6 + 3 HNO3 → WO3 + 6 HCl.

Reaction Implications

This reaction has multiple implications for scientists and engineers because it allows them to create a variety of compounds that have unique properties, including use as catalysts, electrodes, and pigments. For example, studies have shown that tungstic oxide can be used as an anode material in lithium-ion batteries due to its high energy density, making it ideal for powering electronics such as laptops or phones. Additionally, hydrochloric acid can be used as a disinfectant or cleaning product due to its strong acidic nature. Finally, WCl6 can also be used as a reducing agent in organic synthesis reactions.


Tungsten chloride reacting with nitric acid is an incredibly useful chemical reaction with multiple potential applications in fields such as engineering and chemistry. This reaction produces two different compounds—tungstic oxide and hydrochloric acid—that have unique properties that make them ideal for use in products such as batteries or cleaning agents. By understanding this reaction process, scientists and engineers are able to make use of these compounds in their work and create new products or technologies that could benefit society at large.
