On the basis of the general solubility rules given in the table, predict which of the following substances are likely to be soluble in water.
Simple Rules for the Solubility of Salts in Water
1. Most nitrate (NO3-) salts are soluble.
2. Most salts containing the alkali metal ions (Li*, Na*, K*, Cs*, Rb*), and the ammonium ion (NH4*) are soluble.
3. Most chloride, bromide, and iodide salts are soluble. Notable exceptions are salts containing the ions Ag*, Pb²+, and Hg,
2+
4. Most sulfate salts are soluble. Notable exceptions are BaSO4, PbSO4, Hg, SO4, and CaSO4.
5. Most hydroxides are only slightly soluble. The important soluble hydroxides are NaOH and KOH, The compounds Ba(OH)2, Sr(OH)2, and Ca(OH)2 are
marginally soluble.
6. Most sulfide ( S² ), carbonate (CO3² ), chromate (CrO4), and phosphate (PO4*) salts are only slightly soluble, except for those containing the cations in Rule
2.
