Details
Basic
Lead Acetate trihydrate appears as colorless crystals, white granules, or a white powder with a slight acetic odor. It is highly soluble in water and glycerin, giving a slightly sweet taste (note: highly toxic). In dry air, the crystals effloresce, losing their water of hydration.
Common Chemical Reactions:
- Reaction with Hydrogen Sulfide (H₂S): One of its most famous reactions is with hydrogen sulfide gas, yielding a black precipitate of lead(II) sulfide (PbS). This reaction is heavily utilized in analytical chemistry to detect H₂S gas.
- Precipitation Reactions: It reacts with various anions (such as chromates, sulfates, and chlorides) to form insoluble lead salts, making it a valuable precursor in inorganic synthesis.
- Coordination Chemistry: Reacts with isomeric phenylenediacetic acids and other ligands to synthesize lead-based coordination polymers.

Applications
- Analytical Reagents & Test Papers: Serves as the active ingredient in “Lead Acetate Paper” to detect poisonous hydrogen sulfide gas. Acts as a sensitive visual indicator by turning from white to brown/black upon exposure to H₂S.
- Textile & Dyeing Industry: Used in certain dyeing processes. Acts as a mordant and color fixative, helping organic dyes bond securely to textile fibers.
- Chemical Synthesis: Precursor in the manufacturing of other lead salts, lead sulfide nanoparticles, and organometallic compounds. Provides a highly reactive, water-soluble source of Pb²⁺ ions.
- Paints & Coatings: Employed in the production of waterproof paints and varnishes. Functions as a desiccant (drying agent) or catalyst to accelerate the curing process.
Storage Environment Requirements
- Temperature: Store at room temperature (recommended 15 °C to 25 °C).
- Environment: Keep in a dry, well-ventilated area away from direct sunlight.
- Containers: Store in tightly closed, sealed containers to prevent efflorescence and prevent the absorption of carbon dioxide from the air (which forms insoluble basic lead carbonate).
- Incompatibilities: Keep strictly isolated from strong oxidizers, strong acids, strong alkalis, bromates, and phenols.
Handling and Usage Precautions
- Ventilation: Use only under a chemical fume hood or with adequate local exhaust ventilation to prevent inhalation of chemical dust.
- Personal Protective Equipment (PPE): Always wear chemical-resistant gloves (e.g., nitrile), safety goggles, and protective laboratory clothing. A respirator is required if dust is generated.
- Hygiene Practices: Do not eat, drink, or smoke while handling this product. Wash hands and face thoroughly immediately after handling.
- Environmental Protection: Highly toxic to aquatic life. Prevent release into the environment, drains, or watercourses.

FAQ
-
Q: How to get more information about the product?A: You can contact us via email at info@zhpmchem.com or WhatsApp at +8618321309391 for more information about our products and company.
-
Q: Does the product meet our requirements regarding formulation, equipment, and processing?A: Yes, we will adjust the product formulation to your specific needs, ensuring it meets your processing requirements.
-
Q: How does Lead Acetate detect hydrogen sulfide (H₂S) gas?A: When Lead Acetate comes into contact with hydrogen sulfide, a rapid chemical reaction occurs that produces Lead(II) sulfide (PbS). Lead sulfide is highly insoluble and naturally black or dark brown. This distinct color change makes it an excellent visual indicator.
-
Q: Are there special shipping regulations for this chemical?A: Yes. Lead Acetate is classified as a Class 6.1 Toxic Substance under UN 1616. It must be shipped in appropriately labeled, UN-approved packaging. We handle all necessary hazardous materials declarations for domestic and international freight to ensure compliant delivery.
-
Q: Can I request customized packaging or a specific purity assay for my formulation?A: Absolutely. We offer "Package as required" flexibility, from 1kg lab bottles to bulk 25kg drums. If your manufacturing process requires a specific purity grade (e.g., strict heavy metal limits for specialized synthesis), please contact our sales team to discuss custom COA specifications.
