The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
A base and an acid anhydride, e.g., 2 NaOH + Cl 2 O → 2 NaClO + H 2 O An acid and a base anhydride , e.g., 2 HNO 3 + Na 2 O → 2 NaNO 3 + H 2 O In the salt metathesis reaction where two different salts are mixed in water, their ions recombine, and the new salt is insoluble and precipitates.
