The Tungsten AAS standard solution is a clear, colorless liquid with an acidic pH due to the presence of nitric acid. It has a density of approximately 1.01 g/cm³, which is typical for dilute acid solutions. The solution is miscible with water, and its boiling point is around 100 °C, while the freezing point is approximately -5 °C. The solution exhibits a strong acidic odor characteristic of nitric acid, and it is important to handle it in a well-ventilated area to avoid inhalation of vapors.
