6. INSOLUBLE SALTS

7. 1. Definition
2. Preparation of Insoluble
Salts
3. Example of Insoluble Salts

8. DEFINITION
• Solubility of a salt is usually
tested by dissolving a little bit of
the salt in distilled water.
• Salts that cannot dissolve in
water at the room temperature
(27oC) are called insoluble
salts.

9. PREPARATION OF INSOLUBLE
SALTS
Insoluble salts can be prepared
through precipitation method
or double decomposition
reactions.

10. PRECIPITATION METHOD / DOUBLE
DECOMPOSITION REACTIONS
• Two aqueous solutions/soluble
salts were mixed together
• One of the solutions contains the
cations of the insoluble salt.
• One of the solutions contains the
anions of the insoluble salt.

11. • The ions of the two aqueous solutions
above interchange to produce two
new compound which is insoluble salt
or precipitate, and aqueous solution.
• The precipitate produced is obtained
by filtration. The residue left in the filter
paper is the insoluble salt. The filtrate
is soluble salt.

12.  The residue/precipitate (insoluble salt)
then rinsed with distilled water to
remove any other ions as impurities.

PbCl2
Pb2+ ions combined
with Cl- ions to form
white precipitate
Na+ ions and NO3
- ions
do not take part in the
reaction and are free to
move in the solution
Ionic equation : Pb2+ + 2Cl-  PbCl2

16. CHEMICAL AND IONIC EQUATIONS
In the formation of the precipitate of
lead(II) chloride, PbCl2, the chemical
equation can be written:
Pb(NO3)2 (aq) + NaCl (aq)  PbCl2(s) + NaNO3 (aq)
Pb2+ + NO3- + Na+ + Cl -  PbCl2 + Na+ + NO3-
Ionic equation : Pb2+ (aq) + Cl - (aq)  PbCl2 (s)
