Safety Data Sheet for Sodium Bisulfate Solution

Introduction

Sodium bisulfate, chemically represented as NaHSO4, is a white crystalline powder or a colorless solution commonly used in various industrial applications, including water treatment, pH control, and as a cleaning agent. Due to its widespread use, understanding the properties, handling, and safety measures related to sodium bisulfate solutions is essential for minimizing risks in environments where it is utilized.

Chemical Identification

Chemical Name Sodium Bisulfate CAS Number 7681-38-1 Molecular Formula NaHSO4 Molecular Weight 120.06 g/mol

Sodium bisulfate appears as an odorless to slightly acidic solution. It is soluble in water, producing an acidic solution with a pH typically ranging from 1 to 2, depending on the concentration.

Physical and Chemical Properties

- Appearance Colorless liquid - pH (1% Solution) Approximately 1 - 2 - Melting Point Decomposes at approximately 315°C - Solubility Highly soluble in water, forming an acidic solution

Uses and Applications

Sodium bisulfate is used in various applications, such as

1. pH Adjustment Commonly used in swimming pools, food processing, and wastewater treatment to lower pH levels. 2. Cleaning Agent Its acidic nature helps in removing mineral deposits and rust. 3. Laboratory Reagent Used in analytical chemistry as a buffering agent.

While sodium bisulfate is beneficial in many applications, it poses several health risks that warrant attention. Exposure through inhalation, skin contact, or ingestion can result in adverse effects

- Inhalation Dust or mist can irritate the respiratory tract, leading to coughing, sneezing, and shortness of breath. - Skin Contact Contact with concentrated solutions can cause skin irritation, redness, and burns. - Eye Contact Can cause serious eye damage, leading to redness and pain. - Ingestion Swallowing sodium bisulfate can result in gastrointestinal irritation, symptoms of nausea, diarrhea, and vomiting.

First-Aid Measures

In case of exposure to sodium bisulfate solution, it is crucial to take immediate action

- Inhalation Move to fresh air and seek medical attention if symptoms persist. - Skin Contact Immediately wash the affected area with soap and water for at least 15 minutes. Remove contaminated clothing and seek medical attention if irritation persists. - Eye Contact Rinse eyes with water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Seek medical attention immediately. - Ingestion Do not induce vomiting. Rinse the mouth and drink plenty of water. Seek medical help promptly.

Personal Protective Equipment (PPE)

When handling sodium bisulfate solutions, appropriate personal protective equipment should be used

- Eye Protection Safety goggles or face shields to protect against splashes. - Skin Protection Gloves made of rubber or chemical-resistant materials to prevent skin contact. - Respiratory Protection If concentrations exceed permissible exposure limits, use a suitable respirator.

Storage and Handling

Proper storage and handling of sodium bisulfate solutions are crucial to maintain safety

- Storage Keep in a cool, dry, well-ventilated area, away from incompatible substances such as strong bases and oxidizers. - Labeling All containers should be clearly labeled, displaying hazard symbols and relevant safety information. - Spill Response In case of a spill, wear appropriate PPE and contain the spill with inert materials. Dispose of waste in accordance with local regulations.

Conclusion

Sodium bisulfate solution plays an important role in various industrial applications, but it must be handled with care due to its potential hazards. Proper understanding of its properties, risks, and safety measures is essential for workers and users. By adhering to safety guidelines and using appropriate protective gear, the risks associated with sodium bisulfate can be effectively managed, ensuring a safe working environment.
