Decomposition of sodium chloride by electrolysis:
- in water solution: 2 NaCl + 2 H2O = 2 NaOH + H2 + Cl2
- molten sodium chloride: 2 NaCl----------->2 Na + Cl2
2AgCl = 2Ag + Cl2
sodium chloride --> sodium + chlorine
Ag + Cl --> AgCl
2 AgCl → 2 Ag + Cl2
There are many examples of it.... i. AgNO3 + KCl AgCl(s) + KNO3 ii. Ag+ + (NO3)- + K+ +Cl- AgCl + K+ + (NO3)- iii.HCl + NaOH HOH + NaCl iv. CaCO3 + 2 HCl CaCl2 + H2O + CO2
Silver chloride (AgCl) decomposes to form silver (Ag) and chloride ions. This is called light decomposition.
AgCl is relatively insoluble.
Ag + Cl --> AgCl
2 AgCl → 2 Ag + Cl2
The treatment of AgCl involves filtering and washing the precipitate with water to remove any impurities, then drying the AgCl to obtain a solid residue. The dried AgCl can then be weighed to determine its mass and calculate the amount of chloride in the original sample of KClO3. This information can be used to determine the percent decomposition of KClO3.

In breaking-down reactions one substance breaks up into a number of smaller ones. For example, some photographic film is coated with silver chloride (AgCl), a substance that breaks down when light falls on it, leaving a dark image, or negative, on the film. Two products are formed from this reaction, silver (Ag) and chlorine gas (Cl2). The reaction could be written: • as a word equation: silver chloride → silver + chlorine • as an unbalanced formula equation: AgCl → Ag + Cl2 • showing the states of matter: AgCl(s) → Ag(s) + Cl2 (g) Breaking-down reactions are also known as decomposition reactions.
