![]() Note, all sodium, nitrate and ammonium salts are soluble and so we can ignore them in identifying potential precipitates. Looking at the molecular level interactions between water and ions in NaCl. Are silver chloride and silver carbonate precipitates or do they form aqueous solutions? Defining solute, solvent, hydration, dissolution, precipitation, net ionic equation, and spectator ions. Likewise anything in the second column must be soluble, so you have reduced this problem to two questions. By writing the reactants out this way the diagonal represents your reactants and anything in the first or third row must be soluble (Rules 1A), so you can strike them out. This can be done through a matrix, where the rows represent the cations, the columns the anions and the cells the potential combinations: This seems like a very complicated problem (4 salts would result in 16 potential combinations and 5 salts would result in 25) and so we need to develop a technique to see the problem. There are 3 cations and 3 anions which results in 3 2 or 9 combinations (of which 3 are the reactants). About Transcript The solubility product constant, K, is an equilibrium constant that reflects the extent to which an ionic compound dissolves in water. For example, consider NaCl, AgNO 3 and (NH 4) 2CO 3. ![]() For compounds that dissolve to produce the same number of ions, we can directly compare their K values to determine their relative solubilities. ![]() Watch this video for one more example on how to writ complete ion and net ionic equations:Ĭonsider 3 aqueous salt solutions each with different cations and anions.
