Experimentally observed facts have led to the establishment of rules used to predict the solubility of common compounds in water. The rules can be stated as follows:
Compounds that contain , , , and are always soluble with no particular exceptions. Similarly, compounds that contain and are always soluble.
The halides , , and form soluble salts with all the possible cations except for , , and .
All the compounds that contain will be soluble except for compounds that have , , , and .
All the compounds that contain will be insoluble except for those compounds that pair with the alkali metal cations, , , , and .
All the compounds that contain or will be insoluble except for those compounds that pair with the alkali metal cations and .
If you carry out the reaction between table salt () and copper(II) sulfate () in of water, the salt copper(II) sulfate will behave similarly to the salts given in the tab named Slightly Soluble Salts.
Enter the formula for the precipitate, without the phase, that will be formed. If no precipitate is formed, simply type "noreaction" in the answer box.
