Sodium sulfate, or disodium sulfate (Na2SO4), appears as a white crystalline powder. With a molecular weight of 142.04 g/mol, it is stable under typical conditions. Its notable properties include a relatively high melting point of 884 °C and a density of 2.671 g/cm³. When dissolved in water, it demonstrates a solubility of 28.1 g per 100 g of water at 25 °C and shows a neutral to slightly alkaline pH in a 5% solution. Technical buyers often request this grade for its high purity, specifically for applications requiring precise ionic conditions.
