A solution contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2. Can the metal ions be separated by slowly adding Na2CO3? Assume that for successful separation 99% of the metal ion must be precipitated before the other metal ion begins to precipitate, and assume no volume change on addition of Na2CO3.
Solution Terminology Summary Solute and Solvent When solids or gases are dissolved in liquids to form a liquid solution the liquid is called the solvent and the other component is called the solute. When two liquids are combined to form a solution, the one present in the largest amount is usually called thesolvent and the other component is called the solute. In the most general terms, the solute is said to dissolve in the solvent. Concentrated and Dilute A solution that has a relatively large amount of solute per unit amount of solvent is called concentrated. A solution that has a relatively small amount of solute per unit amount of solvent is called dilute. Solubility The maximum amount of a solute tha
