In the chemical industry, 10% sulfuric acid is an indispensable tool used in a variety of applications. As a diluted form of sulfuric acid, it offers several advantages over the concentrated variant and is used in numerous production processes, cleaning applications, and neutralization reactions.

Chemical properties and safety aspects

Sulfuric acid is a strong, divalent acid produced and used in various concentrations. The 10% solution is significantly less corrosive and caustic compared to the highly concentrated form, which greatly facilitates handling and use. Nevertheless, protective measures such as protective clothing, good ventilation, and adherence to safety regulations must always be observed when using sulfuric acid.

Chemical properties of 10% sulfuric acid

• Clear, colorless liquid with a characteristic odor
• Strongly acidic with a pH of about 1
• High conductivity and oxidizing power
• Reacts violently with bases and reducing substances

Safety aspects

• Corrosive to skin, eyes, and mucous membranes
• Can cause severe burns upon contact
• Fumes are harmful and irritating to health
• Fire hazard when in contact with organic materials
• Appropriate protective equipment such as gloves, safety goggles, and protective clothing required

Applications in the chemical industry

The versatile properties of 10% sulfuric acid make it a valuable aid in numerous industrial sectors. Here are some of the main application areas:

Surface cleaning and degreasing

In the metal industry, diluted sulfuric acid is used to remove oils, fats, and contaminants from metal surfaces. It serves as an effective cleaning agent to prepare surfaces for subsequent coating or galvanizing processes.

Neutralizing agent

As a strong acid, 10% sulfuric acid can be used to neutralize bases and alkaline wastewater. It is applied in sewage treatment plants, chemical production processes, and to regulate pH in industrial systems.

Chemical manufacturing

In chemical synthesis, diluted sulfuric acid serves as a reactant or catalyst in the production of various organic and inorganic compounds. Examples include the manufacture of dyes, pharmaceuticals, and fertilizers.

Water treatment

10% sulfuric acid is used in water treatment plants to remove minerals and heavy metals from water. It enables the adjustment of the optimal pH value for subsequent filtration and disinfection steps.

Laboratory applications

In the chemical laboratory, diluted sulfuric acid is used in many ways, such as a titrant, solvent, or reagent in analytical methods.

Safe handling and storage

Although 10% sulfuric acid is less hazardous compared to the concentrated form, safety regulations must always be observed during handling and storage. These include:

• Use of appropriate protective equipment such as gloves, safety goggles, and protective clothing
• Working in well-ventilated rooms or under a fume hood
• Storage in suitable, corrosion-resistant containers
• Separate storage of acids and bases
• Ensuring proper disposal

By adhering to these measures, the use of 10% sulfuric acid in the chemical industry can be made safe and efficient. Its versatile applications make it a valuable tool in numerous production and processing operations.
