Chemical Name: Sodium Tartrate Dibasic Dihydrate
Common Uses: Laboratory reagent, component in chemical analysis, sequestrant, buffer
Chemical Formula: Na2C4H4O6·2H2O
Appearance: Colorless or white crystalline powder
Odor: Odorless
Key Identifiers: Recognized for its high solubility in water, typical of tartrate salts; crystalline texture stands out during handling; known presence in titration protocols
Main Risks: Sodium tartrate dibasic dihydrate usually carries a low health risk based on its lab use and food additive history, but carelessness could still cause problems; dust particles may irritate airways or eyes after spills or during measuring; if taken in larger amounts unintentionally, gastrointestinal discomfort such as nausea, abdominal cramps, or diarrhea may follow
Physical Hazards: Not flammable; not considered a reactive oxidizer; not prone to sudden decomposition
Environmental Risk: Not labeled as highly toxic to ecosystems, but oversight with chemical runoff is never a good idea
Main Component: Sodium tartrate dibasic dihydrate
Concentration: Typically near 100% in reagent-grade supplies
Other Components: Trace water as part of its dihydrate form; any impurity levels remain low in high-purity products
Inhalation: Move to fresh air if dust is inhaled and irritation kicks in; persistent symptoms may call for a checkup by a medical pro
Ingestion: Rinse mouth with water; accidental swallowing in sensible amounts might cause an upset stomach, but large amounts should never be ignored; get medical help if symptoms last
Skin Contact: Rinse off with soap and water; skin contact rarely does much harm, but responding fast stops any chance of irritation getting worse
Eye Contact: Flush eyes thoroughly with water; keeping eyelids open and blinking helps clear out grains; if irritation keeps up, a doctor’s office is the next stop
Fire Risk: Sodium tartrate isn’t a fire starter; doesn’t burn easily on its own
Extinguishing Methods: Standard chemical fire methods work fine: water, foam, dry chemical, or CO2
Protective Equipment: Firefighters feel safest with full gear and a handy breathing device, all the more if unknown chemicals are present
Decomposition: Smoking, high heat, or strong acids could send out irritating fumes like carbon monoxide, carbon dioxide, and sodium oxides
Spill Response: Careful sweeping or scooping keeps dust clouds in check; avoid stirring up fine particles
Cleanup: Use a moist cloth or mop for leftover traces; avoid dumping waste into drains
Ventilation: Open windows help draw out airborne dusts; masks or dust respirators offer further safety when cleaning large spills
Disposal: Place collected solids in a sealed container for later proper disposal according to local rules
Handling Tips: Handle gently to avoid splashing powders into the air; respect good personal hygiene by washing hands after use; food and drink never mix with chemical handling in a lab or stockroom
Storage Needs: Keep containers tightly closed, stored in a cool, dry, ventilated spot; keeping it away from acids and moisture extends shelf life and purity
Container Advice: Use compatible, labeled containers designed for chemicals to prevent cross-contamination
Ventilation: Room vents or fume hoods make a big difference during weighing and mixing
Protection Gear: Dust masks or respirators shelter lungs in case of airborne particles; chemical safety glasses guard eyes from dust splashes; gloves, usually nitrile or latex, block skin contact
Work Practices: Use spatulas or scoops, not bare hands, to measure powders; keep lab coats or aprons handy for extra protection
State: Solid
Appearance: White or colorless crystals or crystalline powder
Solubility: Dissolves well in water, making solutions easy to prepare; does not dissolve well in most organic solvents
Melting Range: Above 100°C (with decomposition); heat can drive off water, leaving anhydrous salt
Odor: Lacks any distinctive smell
Other Notes: Typical density sits around 1.7 g/cm3; stable at room temperature when kept dry
Chemical Stability: Remains stable under normal conditions; avoids trouble except with strong acids or active oxidizers
Avoid: Don’t mix with strong acids; may release carbon dioxide and cause effervescence
Polymerization: Doesn’t polymerize; no odd reactions expected during normal handling
Decomposition: Heating above safe limits can break it down, sending out carbon oxides and sodium oxides
Health Effects: Low acute toxicity according to animal studies and regulatory references; the body clears moderate amounts, but concentrated exposure may irritate mucous membranes or bring on laxative effects
Chronic Effects: Routine exposure leads to mild risk only; evidence linking it to cancer or reproductive harm is slim to none based on public safety data
Sensitization: No solid proof of allergic response from skin contact or inhalation, but following lab safety habits still matters
Aquatic Toxicity: Very low risk for aquatic life based on available data; quick decomposition and dilute use reduce environmental burden
Persistence: Natural breakdown in water bodies speeds up removal; not considered bioaccumulative
Pollution Potential: Letting bulk powder or solutions run off into waterways brings unnecessary strain, so chemical waste collection makes practical sense
Preferred Disposal: Place residue or waste in sealed, labeled containers dedicated to chemical disposal; solid waste paths often start with the facility’s hazardous waste provider
Sewer Ban: Avoid rinsing bulk quantities down the drain, even with its low environmental risk; staying above board with disposal rules heads off long-term issues
Container Cleanup: Rinse containers thoroughly before recycling or discarding, preferably following local or national rules
Hazard Category: Not considered hazardous for transport by ground, sea, or air under most global regulations
Packaging: Use sealable, sturdy containers; labeling clarity speeds up identification and delivery
Special Precautions: Avoid dampness and shocks that could crack open containers or cause powder leaks
Regulatory Numbers: No special UN or DOT number typically applies due to its low risk status
GHS Status: Not classified as a hazardous substance or mixture under current global harmonized standards
Worker Protection: General duty to inform and safeguard workers applies to all chemical handling, so safety data access matters regardless of hazard status
Food Additive Approval: Cleared for regulated food and pharmaceutical uses, though industrial purity may differ
Labeling: No excessive warning symbols needed, but labeling for substance identity and best practices fits well with risk management
