What are three types of salts?
Three types of salts are neutral, acidic and basic salts. The salts that give a neutral solution on mixing and dissolving them with water are known as neutral salts. The reaction of strong acid and strong base gives neutral salt. For example sodium chloride, sodium sulphate.
What properties distinguish salt and water?
The viscosity (i.e., internal resistance to flow) of seawater, for example, is higher than that of fresh water because of its higher salinity. The density of seawater also is higher. Seawater’s freezing point is lower than that of pure water and its boiling point is higher.
What is the chemical equation for salt?
The chemical formula of table salt or sodium chloride is: NaCl. There are one sodium atom and one chlorine atom in each molecule. Note there is no subscript for the number “1.”.
What are the characteristics 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.
What are the examples of salt in chemistry?
Examples of Salts in Chemistry Sodium Chloride. Table salt, or sodium chloride, is the ionic product of the combination of lye, or sodium hydroxide, and hydrochloric acid. Ammonium Dichlorate. Used in lithography, oil purification and some forms of photographic development, ammonium dichromate is an orange crystal. Magnesium Sulfate. Magnesium sulfate is a naturally occurring white crystal, also known as Epsom salts. It is the product of the chemical reaction between magnesium hydroxide and sulfuric acid.
What is the chemical make up of salt?
Salt, table salt or common salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite.
