Safety Data Sheet for Sodium Bisulfate Solution in Laboratory Use and Handling

Sodium Bisulfate Solution Safety Data Sheet (SDS)

Introduction

Sodium bisulfate, commonly referred to as sodium hydrogen sulfate (NaHSO₄), is an inorganic compound widely used in various industrial and household applications. It is a white crystalline solid that is hygroscopic in nature. Sodium bisulfate solution is often utilized for its acidic properties in cleaning agents, water treatment, and pH adjustment processes.

Physical and Chemical Properties

Sodium bisulfate appears as a white granular solid or powder and is soluble in water, forming a solution with a pH level of about 1-2, making it acidic. Its molar mass is approximately 102.06 g/mol. The substance has a melting point of about 315 °C, and the solution is known to release sulfur dioxide when heated, which can pose hazardous fumes if not properly managed.

Health Hazards

When handling sodium bisulfate solution, it is vital to recognize potential health hazards. The solution can cause irritation to the skin, eyes, and respiratory system. Direct contact with the skin may result in burns or irritation, while exposure to eyes can lead to severe injury, including permanent damage. Inhalation of the aerosolized solution may result in respiratory distress, coughing, or wheezing.

Ingestion of sodium bisulfate can lead to gastrointestinal distress, including nausea, vomiting, and abdominal pain. Therefore, it is crucial for personnel handling this compound to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and respiratory protection as needed.

Environmental Hazards

Sodium bisulfate solution poses a risk to aquatic life if released into the environment. It can lower the pH of water bodies and disrupt the ecosystem balance. Consequently, precautions must be taken to prevent spillage and ensure proper disposal methods to mitigate environmental impact. In the event of a spill, neutralization with sodium bicarbonate or limestone may be necessary before disposal.

First Aid Measures

In case of exposure to sodium bisulfate solution, immediate action is required. For skin contact, remove contaminated clothing and rinse the affected area with plenty of water for at least 15 minutes. If irritation persists, seek medical attention. For eye exposure, flush the eyes with water for at least 15 minutes while holding the eyelids open. Medical attention should be sought immediately, especially if there is any sign of damage.

If inhaled, the individual should be moved to fresh air and monitored for symptoms. If breathing difficulties occur, seek medical help promptly. Ingestion of the solution demands immediate medical attention; do not induce vomiting unless directed by a medical professional.

Storage and Handling

Sodium bisulfate solution should be stored in a cool, dry area away from incompatible materials such as strong bases and oxidizers. Containers should be tightly closed to prevent moisture absorption and should be labeled clearly to avoid accidental misuse. It is crucial to handle the solution in well-ventilated areas and to utilize appropriate spill cleanup materials in case of accidental spillage.

Conclusion

Sodium bisulfate solution is a useful compound widely applied across various sectors. However, safety precautions must be observed to prevent health hazards and environmental impacts. Understanding its properties, risks, and proper handling procedures is essential for ensuring safe usage. Always refer to the Safety Data Sheet (SDS) for specific guidelines and first aid measures relating to sodium bisulfate solution.
