Enter your search terms:. Most chlorides are salts that are formed either by direct union of chlorine with a metal or by reaction of hydrochloric acid a water solution of hydrogen chloride with a metal, a metal oxide, or an inorganic base.
Chloride salts include sodium chloride common salt , potassium chloride , calcium chloride , and ammonium chloride. Most chloride salts are readily soluble in water, but mercurous chloride calomel and silver chloride are insoluble, and lead chloride is only slightly soluble. Some chlorides, e. Many metal chlorides can be melted without decomposition; two exceptions are the chlorides of gold and platinum.
Most metal chlorides conduct electricity when fused or dissolved in water and can be decomposed by electrolysis to chlorine gas and the metal. Making insoluble salts To make an insoluble salt, two soluble salts need to react together in a precipitation reaction. The table shows soluble and insoluble salts: Soluble Insoluble All nitrates None All common sodium, potassium and ammonium salts None Most common sulfates Calcium sulfate and barium sulfate Most common chlorides Silver chloride Sodium, potassium and ammonium Most common carbonates We can see from the table that silver chloride is an insoluble salt.
All nitrates. All common sodium, potassium and ammonium salts. Most common sulfates. Calcium sulfate and barium sulfate. Most common chlorides. Silver chloride. Sodium, potassium and ammonium.
