WebThe solubility (by which we usually mean the molar solubility) of a solid is expressed as the concentration of the "dissolved solid" in a saturated solution. In the case of a simple 1:1 solid such as AgCl, this would just be the concentration of Ag + or Cl – in the saturated solution. WebSo in pure water, the molar solubility of silver chloride is 1.3 times 10 to the negative five molar, which isn't very soluble at all. But now we have ammonia present. We've increased the solubility, and we just calculated the molar solubility is .14 molar. And obviously, .14 molar is a lot larger than 1.3 times 10 to the negative five. greater knox family practice boronia
