Nitric Acid 20% – Versatile Uses and Safety Guidelines

Nitric Acid 20%: A Balanced Solution for Industrial and Laboratory Use

Nitric Acid at a 20% concentration is a commonly utilized solution in various industrial processes and laboratory applications. It strikes a balance between efficacy and safety, offering versatility for a range of uses.

Chemical Attributes

At 20% concentration, Nitric Acid (HNO3) is a potent oxidizing agent with a reduced corrosive nature, making it suitable for a variety of controlled applications.

Appearance and Properties

While still a colorless liquid, 20% Nitric Acid is less fuming than its more concentrated counterparts and carries a strong, sharp odor.


This concentration of Nitric Acid is widely used for its effectiveness in controlled oxidizing reactions and as a cleaning agent.

Analytical Reagent

It is frequently used in analytical chemistry for titrations and preparing samples for analysis.

Metal Etching

20% Nitric Acid is often used for etching metals and preparing surfaces for further processing or analysis.

Handling and Storage

Proper handling of Nitric Acid, even at a 20% concentration, is necessary to ensure safety and maintain the quality of the acid.

Safety Precautions

It is important to use personal protective equipment, including gloves and safety goggles, and to work in a well-ventilated area to avoid inhaling vapors.

Storage Practices

Store Nitric Acid in a cool, dry, well-ventilated location, separated from incompatible materials such as organic compounds, alkalis, and reducing agents.


With its considerable oxidizing power yet manageable corrosiveness, Nitric Acid at a 20% concentration is essential for a wide range of industrial and laboratory applications. Adherence to safety guidelines and correct storage practices is paramount for its effective use.
