Solubility of Inonic Substance in Water


Table 4.1 Simple Rules for the Solubility of Salts in Water
(page 150, Chemistry, Zumdahl, 5th ed)

========================================================================
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 (ClO3-), bromide, and iodide salts are soluble. Notable exceptions are salts containing the ions Ag+, Pb2+, and Hg2+.
4. Most sulfate salts are soluble. Notable exceptions are BaSo4, PbSO4, Hg2SO4, and CaSO4.
5. Most hydroxide salts are only slightly soluble. The important soluble hydroxides are NaOH and KON. The compounds Ba(OH)2, Sr(OH)2, and Ca(OH)2 are marginally soluble.
6. Most sulfide (S2-), carbonate (CO22-), chromate (CrO42-), and phospate (PO43-) salts are only slightly soluble.

Table 1 General Solubility Guidelines
Page 437 of Modern Chemistry by Holt, Rineheart and Winston
Chapter 13. Ions in Aqueous Solutions and Colligative Properties

========================================================
1. Sodium, potassium, and ammonium compounds are soluble in water.
2. Nitrates, acetates, and chlorates are soluble.
3. Most chlorides are soluble, except those of silver, mercury(I), and lead, Lead(II) chloride is soluble in hot water.
4. Most sulfates are soluble, except those of barium, strontium, lead, calcium, and mercury.
5. Most carbonates, phospates, and silicates are insoluble, except those of sodium, potassium, and ammonium.
6. Most sulfides are insoluble, except those of calcium, strontium, sodium, potassim, and ammonium.
