Unformatted text preview: ns in solution, the solutions must be prepared from compounds that are soluble. All nitrate salts are soluble. Therefore, the cations you will use will be solutions of their nitrate salts. In keeping with the usage of net ionic equations, only the cation, e.g. Ca2+, will be listed in your data table. For anions, you will formulate a solubility rule which will allow you to guess what an appropriate spectator cation might be.
