## What Is Nitric Acid 68% and What Is It Used For?

Nitric acid (HNO₃) at 68% concentration is classed as a concentrated strong acid and is one of the most versatile industrial chemicals available. At this concentration it’s sometimes referred to as “concentrated nitric acid” to distinguish it from dilute grades used in specific analytical processes.

Common applications include:

– **Metal etching and surface treatment** — widely used in the electronics and metalworking industries to etch copper, clean stainless steel, and passivate metal surfaces
– **Fertiliser and chemical manufacturing** — a key feedstock in the production of ammonium nitrate and other nitrogen-based compounds
– **Laboratory reagent** — used in digestion, analysis, and preparation of samples across chemistry, environmental testing, and mining assay work
– **Industrial cleaning** — effective for removing mineral scale, iron deposits, and oxide layers from process equipment
– **pH adjustment** — used in water treatment and process industries to lower pH in alkaline solutions

Its reactivity makes it highly effective across all these applications — but that same reactivity demands careful handling. More on that below.

## Nitric Acid Handling and Storage: What You Need to Know

Nitric acid 68% is a highly corrosive, oxidising acid that requires strict handling protocols. Anyone purchasing or using this chemical in a workplace setting should be familiar with the relevant Safety Data Sheet (SDS) before use.

**Key handling considerations:**

– **PPE is non-negotiable** — always wear acid-resistant gloves (nitrile or butyl rubber), chemical splash goggles, and a face shield when handling. A chemical-resistant apron or lab coat is essential.
– **Ventilation** — nitric acid releases toxic nitrogen dioxide (NO₂) fumes, particularly when it contacts metals or organic material. Always work in a well-ventilated area or under a fume hood.
– **Storage** — store in a cool, dry, well-ventilated area away from direct sunlight. Keep away from incompatible materials including organics, flammables, bases, and reducing agents.
– **Bunding** — liquid acid storage requires appropriate chemical bunding in accordance with Australian standards. The volume of your storage determines the bunding requirements under AS 3780.
– **Containers** — nitric acid must be stored in compatible containers. It will react with many metals and certain plastics. Use HDPE or glass where appropriate.

Always consult the SDS supplied with your order and comply with your workplace’s chemical management plan.

## Nitric Acid vs Other Industrial Acids: Choosing the Right One

If you’re unsure whether nitric acid is the right product for your application, it’s worth understanding how it compares to other commonly used industrial acids.

| Acid | Concentration | Key Use Cases |
|—|—|—|
| Nitric Acid | 68% | Metal etching, passivation, lab reagent, pH dosing |
| Sulphuric Acid | 98% | Battery acid (diluted), industrial processes, fertiliser production |
| Hydrochloric Acid | 32–33% | Concrete etching, pH adjustment, scale removal |
| Citric Acid | Food/tech grade | Food processing, descaling, mild cleaning |

Nitric acid’s key differentiator is its oxidising nature — unlike hydrochloric or sulphuric acid, it oxidises metals rather than simply dissolving them. This makes it uniquely suited to passivation of stainless steel and certain etching applications where other acids would be ineffective or damaging.

If you’re working in pool water treatment, hydrochloric acid (sold as pool acid or muriatic acid) is the more appropriate choice for pH reduction. For battery maintenance or heavy industrial processes, sulphuric acid is typically preferred. For metal cleaning, descaling, or passivation work — nitric acid is the go-to.

Viva Blu stocks all of these. If you’re not sure which grade or product suits your application, get in touch and we’ll point you in the right direction.
