Silver Sulfate (Ag₂SO₄) is an inorganic silver salt composed of silver ions (Ag⁺) and sulfate ions (SO₄²⁻). It appears as a white crystalline solid and is moderately soluble in water compared to other silver salts such as silver chloride.
Silver Sulfate is primarily used in analytical chemistry, electrochemical applications, and as a precursor in the synthesis of other silver-based compounds. Due to its ability to release silver ions, it also exhibits antimicrobial properties, making it relevant in specialized pharmaceutical and laboratory applications.

Silver sulfate is mainly used in analytical chemistry, electrochemical processes, and as a precursor for synthesizing other silver compounds. It is also valued for its antimicrobial properties in controlled applications.
Silver sulfate can be irritating to the eyes, and direct exposure should be avoided. It is advisable to use appropriate safety measures, such as protective eyewear, when handling it.
Silver sulfate is mostly used as a laboratory reagent, an electrochemical material, and a source of silver ions in chemical reactions. It also has limited antimicrobial applications.
Silver sulfate is commonly known as argentous sulfate or disilver sulfate. It is also referred to as silver(I) sulfate or sulfuric acid, disilver(I) salt, used as a reagent in chemical analysis, particularly in laboratory testing and organic synthesis, and also finds application in electrochemistry and water quality analysis.
Silver sulfate solution is formed by dissolving a small amount of silver sulfate in water, resulting in a saturated or near-saturated solution due to its low solubility.
Silver sulfate has a molar solubility in water at 25 °C of approximately 1.4 × 10⁻² mol/L, based on its solubility product (Ksp ≈ 1.2 × 10⁻⁵), indicating relatively low solubility in water.
