Preparation of Insoluble Salts

Preparing Insoluble Salts

  • Insoluble salts are formed using a precipitation reaction.
  • The solid salt obtained is known as the precipitate. To ensure success, the solid salt formed must be insoluble in water, and the reactants must be soluble.

When two soluble reactants are used, a precipitation reaction occurs. The diagram below illustrates the filtration process to separate the precipitate:

Method

Follow these steps to prepare insoluble salts:

  1. Mix two soluble reactants in a solution.
  2. A precipitation reaction will occur, forming an insoluble salt as a solid.
  3. Filter the mixture to separate the precipitate from the solution.
  4. Collect and dry the precipitate to obtain the insoluble salt.

MULTIPLE CHOICE QUESTION
Try yourself: What is the purpose of the filtration process in preparing insoluble salts?
A

To mix two soluble reactants in a solution.

B

To separate the precipitate from the solution.

C

To collect and dry the precipitate.

D

To form an insoluble salt as a solid.

Example: Preparation of pure, dry lead(II) sulfate crystals using a precipitation reaction

Soluble Salts Used

  • Soluble Salt 1: lead(II) nitrate
  • Soluble Salt 2: potassium sulfate

Method

  • Dissolve lead(II) nitrate and potassium sulfate in water. Mix them well in a beaker using a stirring rod.
  • Filter the mixture to separate the precipitate.
  • Wash the precipitate with distilled water to remove any traces of potassium nitrate solution.
  • Allow the washed precipitate to dry in an oven.

Equation of reaction
lead(II) nitrate + potassium sulfate → lead(II) sulfate + potassium nitrate
Pb(NO3)2(aq) + K2SO4(aq) → PbSO4(s) + 2KNO3(aq)

FAQs on Preparation of Insoluble Salts

1. What are insoluble salts?
Ans. Insoluble salts are salts that do not dissolve in water or any other solvent to a significant extent.
2. How can insoluble salts be prepared?
Ans. Insoluble salts can be prepared by mixing two solutions of soluble salts that react to form an insoluble salt, which can then be precipitated out.
3. Can insoluble salts be separated from a solution?
Ans. Yes, insoluble salts can be separated from a solution through a process called precipitation, where the insoluble salt forms a solid that can be filtered out.
4. What are some common examples of insoluble salts?
Ans. Some common examples of insoluble salts include silver chloride (AgCl), lead(II) sulfate (PbSO4), and calcium carbonate (CaCO3).
5. Why are insoluble salts useful in chemistry?
Ans. Insoluble salts are useful in chemistry for various purposes, such as forming precipitates for qualitative analysis, as catalysts, or as pigments in paints and dyes.
