Solubility of Salts Solubility of Salts Solubility is the ability of a compound to dissolve in a solvent. Table below shows the solubility of the salts of nitrate, sulphate, chloride and carbonate. Salt Solubility Salt of potassium, sodium and ammonium All soluble in water Salt of nitrate All soluble in water Salt of sulphate Mostly … Read more

Preparing Insoluble Salts Insoluble salts can be made by ionic precipitation (is also called double decomposition/double displacement). This involves mixing a solution that contains its positive ions with another solution that contains its negative ions. Example:Write the equation of the reaction that can be used to prepare the following salt: Calcium sulphate Lead chloride Copper … Read more

Preparing Salts of Non-“Potassium, Sodium and Ammonium” The salt non-potassium, sodium and ammonium is prepared by reacting acid with insoluble metal/metal oxide/metal carbonate: Acid + Metal Salt + Hydrogen (Displacement reaction) Acid + Metal oxide Salt + Water (Neutralisation Reaction) Acid + Metal carbonate Salt + Water + Carbon Dioxide Below is the steps in … Read more

Preparing Salts of Potassium, Sodium and Ammonium Potassium, sodium and ammonium salts are usually prepared through the reactions of acids with alkalis. Reaction acid with alkali will produce salt and water.Acid + Alkali → Salt + Water The salt is prepared by titration method of acid and alkali using an indicator. Steps to Prepare the Salts of … Read more

Preparation of Soluble Salts There are 2 things to be considered when preparing a salt: What are the chemical used? How to separate the salt from other substance? Method used to prepare salt depends on the solubility of the salt. Soluble salts are prepared from the reactions between an acid with a metal/ base/ metal … Read more

A salt is an ionic compound formed when the hydrogen of an acid is partly or completely replaced by a metal ion or ammonium ion. All salts are chemically and electrically neutral. Example Diagram above shows that when the hydrogen ion in nitric acid is replaced by Na+, Ca2+, NH4+ or Al3+ ions, salts are … Read more
