Uses of different salts in daily lifeMany different types of salts can be found in nature. The sea contains many salts such as sodium chloride, potassium chloride, magnesium chloride, magnesium sulphate and potassium bromide. The earth’s crust is made up of minerals containing various types of salts such as calcium fluoride (fluorite), magnesium sulphate (Epsom … [Read more...] about Uses of different salts in daily life

General Properties of Salts
General Properties of Salts Some of the characteristic properties of salts are:Melting and boiling points: Salts are mostly solids which melt as well as boil at high temperatures. Solubility in water: Salts are generally soluble in water. For example, sodium chloride, potassium sulphate, aluminium nitrate, ammonium carbonate, etc., are soluble salts while silver … [Read more...] about General Properties of Salts
Preparation of Salts
Preparation of Salts Preparation of salts in the laboratoryThe method used to prepare a salt depends on the solubility of the salt in water. A soluble salt can be prepared from a reaction between an acid and a metal, a base or a carbonate.Reaction 1: Acid + alkali → salt + water Reaction 2: Acid + metal → salt + hydrogen Reaction 3: Acid + base → salt + … [Read more...] about Preparation of Salts
Qualitative Analysis of Salts
Qualitative Analysis of Salts What is qualitative analysis?Qualitative analysis of a salt Analysis is a chemical technique used to identify the ions present in a salt by analysing its physical and chemical properties and hence determine the identity of the salt. It determines only the presence or absence of a particular ion in a given salt. This method does not … [Read more...] about Qualitative Analysis of Salts
Action of Heat on Salts
Action of Heat on SaltsHeating a salt may cause it to decompose. The decomposition may result in (a) a colour change (b) evolution of a gas (c) liberation of water vapour Gases such as carbon dioxide, sulphur dioxide, nitrogen dioxide, ammonia or oxygen can be evolved. By identifying the gas or gases liberated, it is possible to pinpoint the anion present in the … [Read more...] about Action of Heat on Salts
