Silver Nitrate (AgNO3) Standard Solution, 0.01 / 0.02 / 0.1 mol/L, 100 mL / 500 mL

Silver nitrate (AgNO3) volumetric standard solution for precipitation titration (argentometry), determination of chloride in water, salt content analysis in food and monitoring of industrial circulating cooling water. Available in 0.01, 0.02 and 0.1 mol/L concentrations, in 100 mL and 500 mL bottles.

Features

• Prepared and calibrated with reference to GB/T 601-2016
• Made from silver nitrate and ultrapure water
• Strictly prepared in a clean laboratory at 20 ± 3 °C; testing confirms good homogeneity and stability
• Sharp, easy-to-judge endpoint: silver ions react quantitatively with halide ions (Cl⁻, Br⁻, I⁻) in neutral or weakly alkaline solution to form an insoluble silver halide precipitate; at the endpoint, a slight excess of Ag⁺ reacts with potassium chromate indicator to form a brick-red silver chromate precipitate
• Light-protective brown bottle with triple-thread screw cap for a leak-proof seal against external influences
• Packed in a thickened, tear-resistant, moisture- and contamination-proof PE zip bag with a writable surface for labeling

Directions for Use

Use according to your experimental requirements and method. Room temperature changes and water vapor condensation may cause slight changes in concentration, so bring the solution to 20 ± 3 °C and shake well before use. Pour out the required amount rather than pipetting from the bottle to avoid contamination, and close the cap tightly immediately after use to keep out airborne impurities. Once opened, use up within a short period.

Precautions

• Wear protective equipment and avoid contact with skin and eyes.
• May be corrosive to metals; avoid prolonged contact with metal objects during use.
• May be toxic to aquatic life with long-lasting effects; waste liquid must be properly treated or recycled and must not be discharged directly.
• For scientific research use only. Not for clinical use.
