What Are The Physical Characteristics Of Silver Molybdate?

Silver molybdate is a chemical compound with the molecular formula Ag2MoO4. It is a crystalline solid that appears as a yellow powder or yellowish-green crystals. Here are some of its physical characteristics:

1. Appearance: As mentioned, silver molybdate appears as a yellow powder or yellowish-green crystals.

2. Density: The density of silver molybdate ranges from 7.0 g/cm3 to 7.3 g/cm3, depending on its crystal structure.

3. Melting point: Silver molybdate has a high melting point of approximately 940°C.

4. Solubility: Silver molybdate is insoluble in water but slightly soluble in dilute acids.

5. Crystal structure: Silver molybdate has a monoclinic crystal structure, which means that its crystal lattice is composed of unit cells that have different lengths, angles, and symmetry.

6. Optical properties: Silver molybdate has interesting optical properties, such as birefringence and photochromism. Birefringence refers to its ability to split light into two polarized beams, while photochromism means that it can change color when exposed to light.

7. Thermal stability: Silver molybdate is relatively stable at high temperatures and can withstand thermal decomposition up to ~300°C.

In summary, silver molybdate is a yellowish-green crystalline solid with a high density, high melting point, and interesting optical properties.
