ATAGO sulfuric acid refractometer in laboratory concentrated sulfuric acid concentration - Database & Sql Blog Articles
In the chemical industry, sulfuric acid is an essential component and catalyst used in many production processes. The concentration of sulfuric acid directly affects product quality, making it crucial to monitor regularly. While various methods exist for measuring sulfuric acid concentration, most companies rely on the metathesis reaction followed by titration. This method involves calculating the amount of reactant and determining the sulfuric acid concentration accordingly. However, this process is often time-consuming, labor-intensive, and prone to variability.
Instead of traditional methods, modern approaches leverage physical properties such as refractive index or conductivity to determine concentration. One widely used tool is the refractometer, which measures the critical angle of light passing through the solution. The ATAGO QR-HSO handheld refractometer is a popular choice for its accuracy and ease of use. It provides digital readings with automatic temperature compensation, ensuring reliable results even under varying conditions.
The ATAGO QR-HSO refractometer is specifically designed for sulfuric acid measurement in industrial and chemical applications. It allows one-handed operation, minimizing direct contact with the acid and enhancing safety. Its compact design makes it portable and suitable for use in tight spaces. Compared to other concentration meters, it offers a cost-effective solution without compromising on performance or durability.
Key features of the ATAGO QR-HSO include:
- High-definition digital display for clear and immediate readings
- Factory-calibrated with automatic temperature compensation for accurate measurements
- Compact and lightweight design for easy portability
- Resistant to strong and weak acids, ensuring long-term reliability
Sulfuric acid is a vital raw material in numerous industries. It is used in the production of fertilizers, phosphoric acid, hydrochloric acid, and sulfur-containing compounds like dyes, surfactants, fibers, and pharmaceuticals. It also plays a key role in manufacturing plastics, rayon, viscose, titanium dioxide (used in paints), sodium sulfate (for glass and detergents), and aluminum sulfate. Additionally, it's a major component in battery acid and desiccants, and is commonly found in acid tanks at steel mills.
The chemical formula for sulfuric acid is H₂SO₄. It is a colorless, odorless, oily liquid with strong hygroscopic properties, capable of mixing with water in any proportion while releasing a significant amount of heat. When concentrated sulfuric acid comes into contact with cotton fabric, it can destroy it instantly. To adjust the concentration, SO₃ is absorbed, and then diluted with water to reach the desired strength. Therefore, continuous monitoring of sulfuric acid concentration is essential during this process to ensure both safety and efficiency.
